2019 reflection

So, another year has gone by. I'll talk about some stuff that is not just about how technical the combo is for once.

I will emphasise that I do not have talent for learning pen spinning. In 2008, I used about 3 hours a day for over 6 months to get from 3 busts to 8 busts. I used 3 hours a day for an entire year to get from palmspin fl ta x 3 (in late 2009) to x 11 (in late 2010) and to x 33 (in late 2011). There were a lot of spinners with fast progress in their first year of spinning, like luxray (6 months)mist (6 months)tigeroat (6 months)A13x (8 months)mksft (1 year)s777 (1 year)vitaly (1 year 1 month) and many more. As a beginner, I was very jealous of these spinners. Mist 6 month solo (linked previously) nearly drove me to quit, if not for a friend (who was not a spinner) saying 'I think you're amazing too'. I was very immature as a person and also had absolutely no idea of PS back then, so I thought a lot of stupid things. 

When I first started pen spinning in late 2007, my first dream was to enter world tournament. After spinnerpeem rose to prominence in 2008-2010, my second dream was to match his lead over the rest of the world in power tricks. I was able to enter WT in 2011 and got an idea of how distant truly skilled spinners were (supawit, s777, sponge, snow etc). In WC12, I faced fel2fram in R6 and was even more surprised by the distance of a true genius from everyone else. I continued joining competitions after that (WT13, WC14, WT15) and improving gradually, however my understanding of PS did not change much in that period. Some time in the middle of 2016, I had around 30 power trick world records, which meant the realisation of my second dream. A few months later, when I was filming for 'this is power V5' in October 2016 and struggling with tricks far more difficult than ones I'd tried previously*, I came to appreciate that true enjoyment came from pushing the boundaries of this artform and using this to inspire other spinners.

*October 2016 was probably first time I spent dedicated effort into using 30-60 minutes to film short sequences of hard tricks lasting 4-8 seconds. WT17 taught me the importance of early preparation, and losing WT17 taught me the importance of distributing material. Filming for 10 year solo encouraged me to expand my skillset and allowed me to make a project I had truly put my heart into. Around May 2018 after watching dary vine compilation, I realised the significance of focusing on density and the implications this had for technical spinning. From July to August of 2018, I participated in SCT (tournament organised by PSH), PSO 2 hands while preparing for my final exams of medical school. I was able to hone my preparation and time management skills well. 

From October 2016 onwards, my interest in victory or loss in competitions has decreased steadily. When I saw the results for WT19 R5 and R6, I did not feel anything at all. Ironically, I had far exceeded any dreams I had for this hobby, but by the time I had gained the ability to do so, I came to value different things. All of my most treasured memories of spinning are from exploring different tricks or approaches to spinning, and from meeting my friends in other countries. Nonetheless, I will probably still join WT21 because 'it is more fun for me to join than not to join'.

I feel that the aim of competitions, collaborations and other events in PS are to encourage development and stimulate discussion in the community. A lot of people think that WT is meant to 'find the best spinner' or something like that, which I disagree with. There are far too many variables (what aspects people prioritise, how judges interpret the criteria, the type of spinning that is more common that year, luck in matchups and so on) for WT result to mean much. This does not mean that the efforts of competitors in WT are meaningless or that WT results are entirely meaningless. However, one should consider these various factors before they decide how significant the results are.

Incidentally, I noticed I am first full time worker to win a world tournament. I've been working as a junior doctor in the hospital with the worst rating for wellbeing and workload in my state, and somehow managed to keep sleep deprivation at a moderate amount only while maintaining decent spinning practice. As far as I know, previous winners were high school or university students.

A lot of people see pen spinning as 'just a hobby'. To me, it is just a matter of resource distribution - if you make good use of your time, you can put sufficient time into full time work/full time study, one 'deliberate' hobby where you use active practice, one 'passive' hobby that does not require dedicated practice, and have enough free time for other life commitments. You use these different things to take breaks from each other (for example, I would take break from pen spinning by reading novels).

To make good use of time, setting up daily routine is essential - e.g. waking up at same time, shower in the morning to get hands warmed up for spinning, studying while on public transport, spinning before sleeping, and sleeping at similar time every day etc. Reducing the amount of time done doing things that do not contribute is vital (like randomly refreshing social media every few minutes).

Admittedly, the time and effort I put into pen spinning is higher than what most people would put into a hobby (I usually woke up at 4:20-4:30am to practice before going to work), and managed to maintain 6 to 6 1/2 hours sleep on most working days. In the week before WT19 final round deadline, I had 2 overtime shifts (working over 13 hours, from 8:00am to after 9:00pm) - to ensure I had decent training time, I woke up at 3:30 am to spin 2 sessions (total 2 to 2 1/2 hours). I have no regrets. In fact, I wake up around 4:20-4:30am to practice even when there is no WT. Average daily practice time on working days would be around 3 hours. 

To any spinners aiming to enter prolonged tournaments, early preparation is the strongest strategy (it becomes more important if you have more life commitments/other things to do). By rough estimate, a combo that took me 3 weeks to reach early this year can be beaten by one that takes 3-4 days of practice late this year. As such, you can exceed the level of a stronger spinner by preparing earlier, and also reduce recycling material.

WT19 taught me that there are always more things to explore in PS, no matter how much I improve my skill and knowledge. I get enjoyment from improving and exploring, so I practice to increase my enjoyment. 

Once again, thanks everyone for their support. I hope my videos were able to surprise you.

I will be a bit less regular in uploading videos for the first few months of 2020, to prepare for solo video. See you again soon!

WT19 R6 combo

Well, it's finally the end of this tournament! There was a lot more material I wanted to use for this round, but it was not developed enough in practical skill or mental foundation, so I ended up sending a backup combo (sorry, haha). The theory behind the 1p2h concepts used is not that remarkable, but the difficulty has been increased a lot.

Nothing is wasted, anything that was not developed enough will be trained further for solo and future videos.

In terms of notation, ' denotes non-dominant (left) hand's finger, i.e. 4' is left hand's pinky, 3' is left hand's ring etc. Apologies for no 120 fps videos, the phone I use to record them has screwed up despite factory reset.


0:01 - 0:03: ?charge 44' - ?inverse twirl 44' - inverse twirl aerial 33'

I've used a similar idea to transition from both hands PU --> both hands PD in previous 1p2h combos. In this combo, it is done with both pinky fingers. In order to get this sequence usable, the order of skill mastery should be:
1. twirl fall (takes 3-6 months of dedicated practice at a minimum) and easier form of the PU --> PD transition using thumb (3-4 weeks to do without breaking pacing)
2. inverse twirl rise (2-3 months of practice) and harder form of the PU --> PD transition
3. combining above skills to usable level (1-2 weeks practice)

0:03 - 0:04: twirl 11' - twirl 42' - pass T2'3' - TT'1' - (palms facing each other) twirl TT' - 22' - 2h wiper release 22'

Fairly easy sequence with twirls and passes. A fast way to transition from having pen held near centre to being held at end (i.e. from regular material to 1p2h wipers).

0:05 - 0:06: 2h wiper release 22' to 11' - RH mirrored powerpass rev + LH inverse powerpass

2h wiper to ?counter/direction change 11' to transition from perpendicular (?) plane of rotation to anticlockwise plane of rotation. Also not particularly difficult, but shows that 1p2h can allow a large range of effects beyond those in 1p1h.

0:07 - 0:10: left hand palm down fingercross square pass - right hand interrupted inverse mirrored powerpass rev

Hardest ending in any of my WT19 combos (approximately as hard as second half of my R5 combo). Of note is the entry into the ending powerpass: it starts as a mirrored pinky spread reverse (i.e. by hitting back of pinky). Usually this powerpass is entered after a full fingerless pinkyaround, which is far, far easier.

Palm down fingercross square pass learning path:
1. pass reverse 23-14-23-14
2. fingercross 23 around (several days)
3. fingercross square pass by combining 1. and 2.
4. palm down fingercross square pass decently (3+ months)

Interrupted inverse mirrored powerpass reverse learning path:
1. inverse mirrored powerpass reverse (in basic form with fl pinkyaround entry, several weeks/months, depends a lot on how strong your technical skill foundation is).
2. interrupted entry - ?years? I started doing this trick around February, and was practising it quite regularly throughout this year - if your technical skill is comparable to mine at start of this year, then it can be expected that you will take 9-10 months to be able to use this idea consistently enough I guess.

I learnt a lot from this WT, see you next year!

WT19 R5 combo

Please use the 120 fps slow motion with subtitles. I’m unsure of the naming for some tricks.




1st block 0:01 - 0:04 (120 fps video 0:01 - 0:12)

Pinky fxxk 34 ~ sonic 23-24-14 (sonic has total 1.0 rotations) ~ 14 pushed index fxxk aerial ~ curled b1b2 fl fxxk ~ pd fl ra 0.5 ~ pd fl ma to 24 (catch ring out)

The pinky fxxk ~ sonic 23-24-14 is not that hard, but uses fingerswitches/hybrid to condense several tricks into less rotations, and makes the 14 pushed index fxxk aerial more difficult.

Back in February, it took a total lucky try to do the 14 pushed index fxxk aerial ~ b1b2 fl fxxk once (I was not able to link it to pd fl around), and I was not able to do it again in the next few weeks.

b1b2 fl fxxk (pen does not go around any finger) is different from the curled index fxxk in R3 (pen goes around curled index). Very difficult to control the conic rotation.

Doing pd powerpass segment after curled b1b2 fl fxxk was also extremely tough to learn, because of the change in angle of rotation required after the earlier difficult material.

Collectively, this block is tied with the 3rd block (0:07-0:11) as the hardest linkages I’ve ever used.

2nd block 0:04 - 0:07 (120 fps video 0:13 - 0:24)

pd fl ma to 24 (catch ring out) ~ inverse side sonic rev (ring out to in) to 34 ~ ?vertical plane pd angled fl pa to 14 (catch mid in, ring out) ~ 14 pushed curled index-mid bust 14-b1 ~ fist bust fishing b1 ~ pd fl pa rev to 24 (catch ring out) - pd ma rev 1.5 24-b1b2

The ?vertical plane pd angled fl pa is intended to change direction of pen’s rotation without there being any obvious direction change. Using a different plane of rotation allows this to happen.

In late 2018 when I visited Japan, I remember discussing pd fl pa rev with ennis at a gathering. It’s been a while, but I’ve finally used it in a combo properly. To train for this linkage, I trained pd fl ia rev to x 10 to set foundation for doing pd fl pa rev cont, which I got up to x 5. Catching in 24 increases the difficulty significantly.

3rd block 0:07 - 0:11 (120 fps video 0:25 - 0:41)

b1b2 pushed ?ia release ~ pinky bust to 14 (catch mid in, ring out) ~ ?invisible direction change wiper 14 ~ neobak - curled pinkybak 1.5 - curled pinkybak 1.0

The b1b2 push for ia release required a bit of practice to do without breaking pace.

Not sure about the name of this type of wiper, it is probably a hybrid of 2 wipers. A bit like figure 8, but figure 8 does not have any direction change.

I had to train curled pinkybak 1.5 for a few months to get 1.5 x 4 - 1.0 as foundation for using it as ending in this way. The critical part is the fact that the ?wiper from 14 leading into the interrupted neobak makes doing curled pinkybak 1.5 extremely difficult, because the wiper has conic spin that moves in a different plane to neobak.

Combo commentary:

In difficulty, mechanics, density, and linkage planning, this combo is worlds above anything else I’ve ever made. I planned this combo mostly in Jan/Feb and was trying parts of it occasionally at that time. I started focusing on it around June, and it took until August with several remarkable jumps in skill and 28 times landing this combo in total (12 on cam) to get the chosen draft.

It used more time to get these 10.1 seconds for R5 than it did to do my entire 10 year solo. As a rough guide to difficulty - the average difficulty of each block described below is similar to my entire R2 combo. Pen spinning difficulty works exponentially, so R5 is R2 cubed. Similarly, I estimate R5 is approximately R3 squared.

Previous posts about R1-R4 combos say things like ‘this is hardest link I’ve shown’ or ‘this is hardest combo I’ve released so far’ - which are true, but a bit laughable when considering the significant gap between those videos and R5.

Aims when making this combo for maximum density and integration:
Every transition from one trick to the next one must be a hybrid with some difficult mechanic
You cannot use the same mechanic for any transitions more than once - e.g. if you use a side sonic, you cannot use side sonic variations again.
Extra requirement: you cannot reuse any mechanics used in previous WT19 combos unless substantial modification has been made, i.e. any similarity would have to be limited to a single transition with different mechanics before and after.

There are 3 instances in the combo which may not fulfill the above requirements -
fist bust fishing: a bit like R4 ending, but has different tricks before and after
pd fl pa rev to 24 - pd ma rev 1.5: maybe not a hybrid but has a difficult mechanic
curled pinkybak 1.5 - curled pinkybak 1.0: uses a similar mechanic twice

Additional thoughts:

Despite the excess arm motion, the actual technique of the tricks is satisfactory when considering the interaction of the pen with the fingers, and the pacing is generally sustained. I’m not sure how much arm motion can be reduced for these tricks, maybe I’ll try it again in a few years’ time. The border between good chaotic effect and bad chaotic effect is very subjective.

There were discussions in WC12 about fel2fram’s execution, with many judges giving him high exec in WC12 (4-5/5). However, he was penalised heavily in exec during WT13 R4. His exec definitely could be cleaner, but the effect he created with more chaotic exec contributed positively to me. There are detrimental mistakes at times, e.g. pen going offcam; but many of the flaws helped to give the combo a unique impression.

One of UPSB’s WT13 judges (nickname: casual, who was mainly an mx spinner) said something like ‘fel2fram’s R4 is very underrated, it is remarkable to be able to do that material at all’.

I first considered having a full hybrid combo fulfilling aim 1. back in late 2018 when I was filming clips after SCT and PSO. It took about a year to improve my physical and mental skill to actually do it.

10 year solo was the realisation of a sentimental dream - to create a video that I could look back on fondly no matter how much time passed. WT19 R5 is the realisation of a technical dream - to fulfill conditions 1. and 2. to maximise density, integration and 3. for creativity. I wanted to execute it better and there’s still a lot further to explore, but this combo is one I can be happy saying I poured my soul into. Creating this combo has more worth to me than any win or loss result.

The type of combo that WT encourages is different to the types of combos that themed competitions, solo or CV creates. A solo is aimed at displaying a large range of skill rather than having 1 or 2 combos outclass everything else, so it is more practical to produce many combos with 2-3 weeks’ effort each. Only in WT (or possibly CV with established release date and elaborate preparation like JapEn) will a combo taking several months of work be encouraged.*

I hope this video was able to leave an impression on you. I will keep waiting for the one who will surpass me.

NB: if you can’t do any of the linkages, your exec is automatically zero. Come back after you’ve accumulated 5 million more drops** of practice.

*of course, if you have the discipline, you can try making a 3-month-effort combo regardless of situation

**if you drop once every 3 seconds and spin 2 hours per day, that’s 876,000 drops in a year, so it will take a bit over 5 ½ years to get 5 million drops.

WT19 R4 combo

Finally pulling out truly hard material this round. I haven't made any fl combo over 10 seconds for quite a while.


The difficulty is far higher than R1-R3
- hardest material shown in those videos is R2's ending linkage and R3 hardest linkage (R3 0:03 - 0:06)
- R4 can be considered as 4 sections as outlined below, 3 of which are of comparable difficulty to those sections

0:01 - 0:04
indexspin ~ index mid mirrored powerpass reverse ~ ring pop ~ arm bounce
- extra 0.5 spin on index

mid ring mirrored powerpass reverse - triangle pass 234 - powerpass 23-34
- a lot harder due to arm bounce entry
- maintaining control and speed for the triangle pass is probably hardest part of this link


0:05 - 0:08
hai tua ~ palm down fingerless pinkyaround reverse (fingers closed) - palm down fingerless middlearound reverse (fingers open) ~ mirrored fingerless middlearound reverse ~ ring spiderspin
- highlight sequence of this combo: proper integration of pd fl around rev into fl combo without any catches in between
- different mechanics in doing the pd fl around rev with fingers closed and fingers open
- mirr fl ma rev ~ ring ss requires hitting pen from other side (see slomo, it is far harder to do this than ordinary fl ma ~ ring ss)

0:08 - 0:10
index mid mirrored powerpass reverse - inverse mirrored powerpass reverse - fingerless indexaround - spiderspin
- the visual effect of the inv mirr pp rev contrasts with previous material
- the easiest sequence of this combo


0:10 - 0:13
fist bust fishing - fist bust x 2
- doing fishing like this requires changing angle of pen's rotation during difficult tricks (see slomo)
- fist bust typically rotates fairly horizontally, whereas the fishing part has pen spinning diagonally
- around 1/4 to 1/5 chance of doing fist bust x 2 successfully in this sequence (compared with just doing x 1)
- made more difficult by being ending

As far as I know, this is first time this material has been used in complete fl combo - only idea that has been used in previous tournaments was the wrist bounce. This is the first combo in this WT where fairly high proportional of my difficulty capacity has been shown (as opposed to R1 fourth root, R2 third root and R3 square root).

Aside from the difficulty, the variety of mechanics in the fl linking is quite large. To use this kind of material effectively throughout a combo, every sequence must feel like a highlight, while also displaying different visual effect.

Unfortunately there are several areas of relative filler (the powerpass 23-34 in first sequence, and the fl ia ss before the ending). Otherwise, the material shown has sufficiently high density for my current ability.

Sorry for hair on frame, hopefully I can pass despite that.
R5 is another step above this combo, so I am praying for victory.

WT19 R3 combo

R3 is a cardioid-based combo, aiming to use wipers in a different way to existing videos while increasing difficulty and density. Difficulty and mechanics shown are considerably more advanced than R2. 0:03 - 0:06 section was quite hard to learn, and is the most difficult linkage I have shown to date.


0:01 - 0:03 flush sonic + inverse side sonic wiper 14-24 - side sonic 24
- ring finger moving from out → in → out


0:03 - 0:04 Tb1 pushed palm down curled index-middle around ~ palm down fingerless middlearound to 24 (ring out) - 24 wiper
- different use of curled finger, no one has used curled PD around like this before to my knowledge



0:04 - 0:06 24 wiper (ring out) - curled index fxxk to 14 (catch mid in, ring out) - angled wiper 14-12
- fxxk cardioid, but with index finger curled for the fxxk
- caught in 14 with the finger position used increases difficulty significantly
- having this linkage right after the previous one also increases difficulty due to there being consecutive hard elements without filler in between


0:06 - 0:08 vertical plane wiper (clockwise) 12-14 (mid out, ring in) > fingerswitch to mid in, ring out > pass rev 23-bt2
- fingerswitch is subtle, not particularly hard though 

0:08 - 0:09 raimo bak rev + ipba rev 24-14 (catch mid in, ring out) > wiper 14 + pass rev 14-23
- hard linkage based on pinky bust cardioid to 14 + inverse side flush sonic


0:09 - 0:10 mid spread 23 > vertical plane wiper (counterclockwise) 23
- unusual linking of this type of wiper, based on mid spread cardioid idea
- this is power V6 compilation has a clip of pinky spread cardioid, but I am not good enough to use it in combo yet


0:12 - 0:14 pinky bust cardioid x 2
- first time this trick has been done cont in combo to my knowledge
- difficulty increased due to being ending


While I was practising, the success rate of 0:03 - 0:06 linkage by itself was worse than 1/20 initially, with improvement to around 1/6 to 1/7 at time of filming (about 200 tries of 0:03 - 0:06 section to determine this result).


The ending consistency was still absolutely terrible even when I had raised personal record of pinky bust cardioid, the success rate of training 0:11 - 0:14 by itself was around 1/20 (also used about 200 tries of 0:11 - 0:14 section to determine this result).

I tried filming the combo at several angles, with the submitted angle being the one I was most satisfied with (even though it probably looks a bit funny to some people). 


Exploring different trick families is really fun =D

WT19 R2 combo


This combo was created with aim of using the 8 main powerpasses with different modifiers for each of them.


In WT17 R2, my combo used 8 powerpasses but with very poor integration and no modifiers.

As such, WT19 R2 represents an advance in the way I consider spinning and combo construction, with increased appreciation of density, integration and visual effect.

Outlined below are the links and modifiers for each of the powerpasses:

0:01 - 0:04

1. pinky fxxk - angled pp
   - pp done in same plane of rotation as fxxk
2. ia rev ~ fl ma rev 1.0
   - around rev 1.0 concept used with pp rev - credits to key3 for around rev 1.0 method
3. ring pushed ss 1.0 - fl pa
   - mid ring pp with +0.5 rotation on first push

0:04 - 0:08

4. inv mirrored pp rev pinky-ring 34-23
   - inv mirrored pp (no additional modification)
5. inv side flush sonic 14-23 ~ palm down mirrored pp 23-T1
   - mirrored pp, but palm down

0:08 - 0:11

6. pd ta ~ pd fl ta ~ thumb inv pp T3-T4
   - thumb-pushed inverse powerpass - credits to taeko for t-powerpass concept
7. raimo bak to 24 ~ inv side sonic 24-14 ~ ra rev 14 ~> fl ia rev to T1
   - powerpass rev on ring and index (skips middle), initial force from push by 14 slot
8. palm down mirrored pp rev T2-2-3 - pd fl ta catch
   - mirrored pp rev, but palm down - applied as fl/power mechanics*
   - this trick requires the ring finger to hit the pen during its rotation, which makes it a lot harder than palm down around 1.5
   - hard to appreciate in normal speed, so here is a clip in 120 fps x 0.5 (i.e. slowed to 1/8th of normal speed)


But it's barely 10 seconds?!! The combo has basically zero filler or breaks, and is done at consistent tempo. Main personal criticism is the excess hand movement at start, otherwise I am largely satisfied with this being a reasonable draft.
Condensing material with consistent difficulty, removing filler segments and even most filler slots (i.e. attempting to have every transition be a useful hybrid) is far harder to sustain than longer, less dense combos.

This combo is harder than WT19 R1 and harder than my SCT18 R4, which was considerably harder than any of my WT17 videos.
Of course, I still have material and capacity saved for future rounds.

Hoping I will pass, best of luck to other participants!

*I am aware pd mirr pp rev has been done with varying cleanness by at least 3 other spinners. As far as I know, this is the first performance of it done as an fl trick (i.e. not caught immediately in a basic slot), and with acceptable technique and plane of rotation
If you have downloaded the clip with the link provided on youtube, you can play it frame by frame and see that the pen does correctly hit ring finger. You can also use the 120 fps slomo above.

WT19 R1 combo (2p2h theory)

Hello everyone, it's been a over a year since I last posted here.

The 2p2h concepts I'll outline in this post are largely paraphrased from what I remember about a post Zombo made back in UPSB V3 era (2007-2010 or earlier). As far as I know, there have only been several short clips or brief applications of these ideas in the past by s777, eriror and tmrw; but not really any complete combos that use varying degrees of synchrony.

Synchrony: happening at same time.

I'm still not sure about what the difference in asynchrony or desynchrony is, so I will be using 'asynchrony' to represent opposite of synchrony (i.e. different things happening).

As inspired by musical theory, there can be varying degrees of discordance (i.e. difference in effect) in what each hand does.




i. The most basic 2p2h is perfect synchrony (no discordance) - where each hand does the same tricks at the same time. This is fairly boring and quite simple, but it can be expanded with transfers like below at 0:27:


ii. Slight discordance - same palm orientation, similar tricks in same slots with slight variation  (e.g. doing inverse sonic 34-23 in right hand and sonic 34-23 in left hand). I made a combo with this concept in 10 year solo at 1:31

iii. Moderate discordance - different palm orientation, similar tricks (e.g. doing sonic 34-23 in right hand with palm up, and sonic 34-23 in left hand with palm down). I made a combo with this concept in PSO18 2 hands R1.

iv. Above moderate discordance - different palm orientations, different tricks but with similar changes in motion (e.g. having right hand go from palm down to palm up, and left hand go from palm up to palm down). I made a combo with this concept in 10 year solo at 0:43, tmrw's WC14 qualification combo also applies this.

v. High discordance - different palm orientations, different tricks, different changes in motion and pen spinning in different planes of rotation. This is probably the hardest form of 2p2h (assuming other factors are equal), and most difficult to achieve a cohesive effect with.

In my WT19 R1 combo, 0:01-0:03 has moderate discordance, 0:04-0:07 mainly has slight discordance; 0:08-0:13 has above moderate and high discordance.

It is tempting to consider 2p2h in terms of what each hand does separately, but this is just an initial consideration. Proper depth of 2p2h lies in understanding how the parts fit together.

Besides the consideration of structure, a 2p2h combo is far more difficult than its separate parts. If the breakdown for the right hand part can be done once every 1 minute (1 in 20 success rate) and the left hand part is once every 2 minutes (1 in 40 success rate), then the chance of doing the parts successfully one after the other is 1/20 x 1/40 = 1/800 (once every 2400 seconds = once every 40 minutes). However, it is more difficult to do the breakdowns at the same time, so the difficulty is even higher.

I also put some basic fingercross with left hand at 0:06 and 0:12, but it's just a minor addition to the overall picture.

I have very high respect for Zombo for documenting these theories so long ago, and I thank all pioneers of 2h concepts for giving me inspiration.

Looking forward to seeing people explore 2p2h more in the future! 2p2h does not usually do well in WT, so I hope I can pass to next round.
