* AC bair will true combo to rest if
a) you land in range (obv)
b) you land before they do (even if by a frame. You basically have to be actionable before they are and you will both enter normal landing lag (you by ACing and they by canceling hitstun with a land)
This works best at %s around 20 but is very DI dependent etc
* Because you can jump during bair's IASA frames, SH bair dj rest is theoretically possible. It looks really wonky, haven't experimented much yet.
