So I don't know if this has been found but I got a 51% no meter with full chargeup. This is probably the easiest setup there is for it too. In the corner, no jump in, and off of his 1,1,3 overhead. The only thing that might vary is ~1% depending on your timing for the bicycle kick and how many actual kicks you can get in.
Without chargeup, the combo will do about 30% damage since he can't hit the second uppercut, so I wouldn't say it's best to this combo if you don't have a full charge since I think there are better combos out there.
