Hi.
I can do most combos. But I have no clue how to reliably connect

(charge)

,

(charge)

(so far no probs) WITH Standing HP (last step is my problem, usually it is followed with

PP and the combo goes on). I only manage to do it with multiple HP inputs, like at least pressing 4x HPs very fast, in most cases in comes out too late or not at all. If I delay, the enemy already hits the floor and I miss, too. Keeping pressing turbo button does not help either.
No idea when watching Vespers or the Hit box video of Takuma either.
Any help appreciated.
