It’s pretty difficult to do, but I just double-tap the jab. It’s something I have to practice pretty consistently to get the proper motion. Ideally you want to be able to put the jab for the special 3 frames in a row as tight as you can. frame 1 press jab, frame 2 release the jab, frame 3 press the jab again. In theory that’s the best way to perform it reliably, in practice it’s pretty damn difficult. I have noticed that the timing feels a lot easier offline than online. I can hardly get any reversal playing online.
Not sure what you’re looking at 6:05. I just see him do a standard jab uppercut through a fireball.
10:28 Goddamn that combo hurts. I’m able to do the standard version that ends in a fireball, and I haven’t had much luck landing an uppercut at the end. I find that the best way to consistently land the link after the dash punch is to piano either a) all 3 cr.punches in rapid succession, that way you’re sure to get at least ONE of the punches to land, and b) double-tap the cr.fwd, or c) combine that cr.fwd by pianoing it with the cr.rh for a simple combo, or cr.short x uppercut.
