What does acceleration do? It just increases (or decreases) the racket velocity over time and therefore the impact velocity. Do any of these studies show that contact time increases with higher impact velocities? No, they all show that contact time decreases with higher impact velocities.

It doesn't matter if the racket is stationary or not (we are not talking about relativistic velocities ;)). What matters is the impact velocity either this is only the ball or it is v_ball + v_racket. I agree that we might have a slightly longer contact time or rolling contact when we loop...

Of course this slow motion video was shot with 16 kfps otherwise we would not be able to see any of the blade's vibrations. The blade tested is afaik an Avalox BT555. Some measured this with around 1300 Hz (16k / 1.3k ~ 12.3) and this is what we see + some faster vibrations of the blade. On a...

Super Slow Motion Table Tennis Ball and racket physics Shot with 16000 fps. Impact between blade and ball (at 76 km/h ~21 m/s) and blade with long pimples and ball (44 km/h ~12 m/s). Contact time <= 1 ms Impact prediction between ball and racket in table tennis...

Uninspiring or just good enough😉 or They say basically the same: good spin, good speed but less than D09C/Dynaryz ZGX and slower when further away/when hitting hard. That can be both positive or negative. Less errors vs harder to overpower an opponent, safety vs speed and so on.

Not really. Just a couple of hits when it was released. G09C for quite some time maybe 2/3 of its lifespan. Boosted it slightly (nice but not enough) then I used too much and it became too mushy with low trajectory...

It is something special. Just 43g to 44g cut on a 157 mm x 150 mm Bty head for such a hard sponge is special. Codexx has lower trajectory, is not really faster (maybe for a short time until the factory booster has worn off) and it's harder to generate quality shots/spin with the Codexx. C53 is...

Butterfly uses koto, koto, kiri, koto, koto for the Falcima. Result is that it plays a bit like a balsa blade when using high input power. More speed than my YEO with similar weight and thickness but less spin. The Hadraw 5 uses ayous for its core so should be more stable than the Falcima...

Rakza Z is definitely not the slowest but slower than D09C and this is not just because it's tackier than D09C. Codexx EL Pro 52/EF Pro 54 may work but is also from ESN like the RZ. Similar tackiness, a bit harder (52°/54° ~ 39°/40° Shore A vs 50° ~38° Shore A), lower arc, and faster than RZ...

To quote a well-known table tennis playing chemist (PhD): "There are two main types of non-VOC boosters, i.e., paraffin/mineral oil-based boosters like the Haifu Seamoon booster (very popular in Asia) or Falco Tempo Long Booster (popular in Europe/US) or limonene-based boosters."...

Same here. For peace of mind and if in budget H3 Neo provincial orange sponge 39° or Nittaku Hurricane 3 Neo (NR-8701) 1). Maybe 38° if used unboosted. Should make a good fit boosted and unboosted with the Drinkall Powerspin (similar to Viscaria). On an allround blade I would definitely boost...

Rakza 7 and 7 Soft are typical ESN tensor rubbers not classical rubbers like Sriver. Not the fastest nor the ones with maximum catapult but a lot faster and with more catapult than Sriver. Sriver has a sponge hardness of 38° JPN/BTY which is around 48° ESN or 37° DHS/Shore A. Sriver FX and Mark...

Sponge hardness should be similar in theory but I can't say how they feel overall (topsheet + sponge) because I've only used H8-80 and Glayzer 09C for a while.

H8-80 was afair always available with specified sponge hardnesses: 37° and 38° Normal H8 39°, 40° and 41° (formerly labeled with soft, medium and hard) but also available from some shops with 37° (e.g. dhs-729.eu, prott.vip or ttnpp.com)
