Nice findings, this sure clears some things up. Thanks for taking your time
And there must be something wrong with my #R PC, since it feels *really* laggy (8~9f delay at least). Same, but to a less extent, happens in AC+ emulated on Dolphin. The PS3 port is by far the closest to perfection.
I play Baiken, so if I had to describe how it feels to combo a j.P after Tatami it would be:
#R: Must press P, as I hold up, just as tatami recovers
AC+ (Wii): Press P after tatami is gone
AC+ (PS3): Press P during the actual jump, it comes out instantly.
Easiest part by far, problems happens when Airdashing after j.D is needed. The difference is such, that I had to re-work my whole muscle memory when playing on PS3
