I did these a long time ago and never wrote them down because I'm stupid.
F-Smash: 7 frames (after smash)
U/D-Smash: 4 frames (after smash)
Dash Dance: 8 frames (after smash)
True Pivot 1 frame (after smash)
Pivot Grab: 2 frames before through 2 frames after smash
B-reversal: 2 frames
Jigglypuff DACUS: 3 frames
Sheik DACUS: 2 frames
There's probably more, and these are probably wrong. I'll redo them formally this weekend. Might grab the more crazy stuff like gliding and all DACUS links. Feel free to leave suggestions.
