Turns out the combo I did must had BBS 1 hit in there or something since the max regular is 6.1k.
However, I wanted to make 2A hit that under the same conditions meaning no BBS and no gold burst.
Now I've actually succeeded but you'll need the timing of the gods to pull it off. Seriously, near the end you'll have to time j.D at first possible frame for level 3, not THAT hard but right after you'll have to wave dash PF before he can tech then land level 3 and then land another frame 1 level 3 in order to make sure you break 6.6k.
