Jago's HP Auto D Data says S.U. 8 - Active 2- Rec. 32. I watched a replay and saw the following: Hit one lasts 7f, next 18f of nothing until the 2nd hit of the auto double hits at frame 26 and lasts 11f (36frames total). Why does data say active 2f vs 36 in game?
Not all of the frame data in the game is correct, sadly. I would definitely not trust the data for auto-doubles, since heavy autos are definitely active for more than 2 frames.
