You can't get your jump back, only with Up-B.
Also ABK 2 has to be used withing 1 second of ABK 1, it has nothing to do with moves, although tbf if you use a move you aren't gonna get ABK 2
I have a 60% combos that get around 1 second rule frame perfectly.
They work from 0 to about 15% and can start from any WT
beware though. These are probably her hardest combos and are near frame perfect the whole way through.
WT1, WT2 (comboing this is the hardest part because you need to keep your DJ), ABK, UAIR, DJ Backwards Uair, ABK back(BUFFER EVERYTHING AFTER THE FIRST ABK FOR THE LOVE OF GOD because I'm pretty sure it's a 1 frame window), Bair/uair (bair for damage and uair for consistency)
Another good one is
Landing Uair, utilt, FH instant uair (hardest part of the combo due to the sh buffer system) WT, WT2, ABK, ABK, Bair (This one is easier because it doesn't require a perfect double WT but it does help to do a DJ WT out of the uair to follow their DI. Also it never hurts to have your DJ lol)
Btw guys learn to the different hitboxes of abk. The early, middle, and late hit all send different angles. Abuse those to fix your combos and send people where you want. Especially at later %
