I just finished doing her actually. That HP butt jump move that lunges you forward... know the distance that it travels and then do it just far enough away that it connects but a jab from the opponent won't cancel it. When you get to the last 5 matches, try to input as few commands as possible. When the opponent is knocked down and you're waiting for them to get up, either go over there immediately and throw them when they get up or press nothing until they get up and then do the HP butt slam. Sometimes to mix it up do jumping HK and as soon as you land do HP butt slam. Just make sure that after you do an attack that gets blocked, immediately start blocking and then jump back to get some distance between you. And again remember to input as few commands as possible.
lol @ comments, I'm enjoying my purchase

(and racking up that fight money)
