Some more percents for “grounded” supers (except the KKZ):
KKZ = 18% increase
Shinku Hadoken = 23%
Yagyou Dama = 21%
Critical Combo Attack = 21%
Total Destruction: Strike = 25%
Corkscrew Blow = 13%
Kikou Shou= 8%
Only Hado Burst and TD: Strike get as high as 25%. Notice they hit one time. According to the distributive law, a 25% for supers should be the same as 25% of each hit + each hit all added together.
I suspect this doesn’t work for two reasons:
Not all supers keep the opponent grounded.
Supers scale their own damage. I mean on a more complex level than simply reducing the % increase against crouching enemies.
Gill’s Wing super starts off quite powerful and gets weaker at the end. But when I did this test, I managed to block all but the very last hit, which did a nice chunk of damage, more than the last hit normally does.
This would explain why things like Shinku and MGHado don’t get 25%. They get 23% and 20%. My idea is corroborated by the fact that Shinku has one less hit. Kikou Shou and Corkscrew Blow hit even more and end up with an even smaller increase. I do not think the relationship is linear, but I don’t have enough numbers to prove this and I don’t have time for more checks.
Start Q’s Double Deadly and Ken’s Shippu so that their first hits land at the same time (do them simultaneously). Both players wil freeze a bit off the ground in their hit animation. Ken then flies to the other side of the screen and Q goes “Uhh.” and falls down. This proves Q is better than anyone else.
