actually yes, and for me, it's judgment, just after certain numbers, but how I assume you guys are testing it is by just doing the move over and over, not hitting anybody
I've tried it on some people, on final D, in Brawl not melee, and so far here's what I've come up with:
hitting a person with 2, they trip, do judgment IMMEDIATELY after, and about 65% of the time I got a 9
hitting a person with 5, right after the last shock (done on low damages) you dash up to were they would land (oh and on light weight characters) and do judgment right there, and 95% of the time it hit them
hitting a person with 8 on low damage, they go up, and while coming down soon as they are right in front of you, do judgment, 95% of the time I got 4, which send you diagonally, and not too far. dash, jump, and do judgment, 95% of the time i did this i got a 9
again, i did this on light weight characters
hitting them with 7, eating the apple immediately, take a SLIGHT pause, dash, do judgement, 95% of the time I got 9 (side note, they slide about the distance of bowser's length after getting hit by 7)
Now, I'm not sure if it only worked on my wii, i haven't spent more than a couple hours on this, on light weight characters so far because of how far they go after each attack, so go ahead and try it if you want, not guaranteed the same results, but just curious if it works
