I just did this with A.B.A in training mode. I performed a combo like this with the dummy's recovery set to Neutral/Back/Front (all 3, for a more detailed test) and got the miscounted black beat.
MOROHA MODE:
2K, 5S, 2H, j.S, j.H, 41236S.... After I land, I've went from one of the following routes
loop - j.S, j.H (Sometimes had to get start with 5S to keep combo going)
or just for the heck of it (Though this isn't her BnB)
5S, 2S, 412H
I found myself in most occassions going into whichever combos from the Moroha Mode starting combo, that the miscounted black beat occurred =/
