If you’re trying to say that EX Palm -> HP Hadou -> EX Hadou -> LP Hadou -> C.HP xx whatever doesn’t work, then you are incorrect, you can hit both hits of the EX Hadou and combo afterwards.
Fake edit: Whether the damage is worth the meter I can’t say, but stun potential is up there, and c.HP does as much stun as dash punch, so you’re basically adding in the two hits of the EX Hadou (100 stun each hit, 200 extra stun for 1 EX stock basically) to a normal corner combo.
Fake edit 2: Adding up the stun numbers from the wiki I get 950 stun for the following combo: close s.HP xx EX Rush Punch, HP Hadou, EX Hadou, LP Hadou, c.HP, however I believe there are dimishing returns on stun the same as there is for damage and I don’t have a console in front of me to check, but I’ve done this combo hundreds of times both online and off I don’t recall it stunning people, so there has to be some scaling on stun in combos.
