This is precisely the animation that occurs when you hit the uppercut correctly, what gives? His guard is down so he should have taken 22 right? I'm not sure what I'm not seeing here. I'm also really unclear on the methodology. You're pressing up as the star punch is being thrown right? The second up press (and hold) is to manip his guard up for the next punch if anyone is wondering

(ALSO: the game is slowed down a little bit)
