lol J236A/B far enough off the ground on air hit will make them float so i think its possible for low JC>J236A/B loops
edit: so much for that idea, J236C>land>JC>J236A will whiff for some reason, J236B is sorta glitched i think because if theyre a little too high youll get the knockdown which is 1 hit but if you do it at the correct height youll get a really strange looking midair bounce with the wall/ground hit effect but it doesn't count as a bounce and for some reason it does 2 hits, the hitstun on it is reduced alot too but you can link into 5C>jc>JC>JD but ends up doing less damage most likely because of some weird proration thing with the glitched J236B
