More or less, here are the current F-Hime combo routes.
I was mostly right, now that I've been playing I can clear up what she actually does.
Combo route stuff was right, it is indeed based on distance, but I got the combo wrong -
5B > 5C > 6C > 236A > j9[C] > j236A > 22D > j[C] > j236A > 6jC > dj jAC > airthrow/kick/pillar
You can do this midscreen, but the combo is a bit different. In order to understand just how far you can hit this combo from, run the training mode dummy into the corner, then back throw them, and try this combo -
5B > 5C > 6C > 236A >j9[C] > j236A > 22D > j[C] > j236B > 6jC > dj jAC > airthrow/kick/pillar
For midscreen, the 2c > 236b > j[C] combo still applies. You do the shoulder rush ender when you do a j[C] > late airdash jC combo into the corner. You do it with flight, as in 236bb > 22d > jAC > airthrow/pillar/kick.
Be aware that any late airdash combo must be inputted as j[C] > jump > airdash > late jC (but the jump > airdash must be inputted quickly).
