Just-frame combos?

i read u can air juggle ewgf only if u hit the punch on the first frame of his dash AKA just-frame is their a list of moves with this property? i think KUMA has it as well in the corner hunting stance forward+HP can combo 5 times maybe more but it seems to b weird timing u just hunting bear stance, -> HP, HBS , ->HP … ect

edit: sorry its f+HP not back+HP, that is break’n and does not combo up to 5+times

4x = 350dmg 5x=410 dmg with no meter looping the same move in the corner can only do 2 midscreen with maybe a followup
