I read something here at http://shoryuken.com/wiki/index.php/Street_Fighter_IV#Game_Mechanics
"SFIV accepts shortcuts for some of these motions:
- DP - can be performed as DF,D,DF; in other words tap the stick into the lower corner twice. Also DF,D,DB,D,DF,D,DB; in other words wiggle the stick from one lower corner to the other and back.
Useful when you are guarding low, or when you are being crossed up.
- 360 - can be performed as F,DF,D,DB,B,UB or B,DB,D,DF,F,UF. In other words, a 225 degree rotation ending in up and back or up and forward. Reduces the chance of jumping."
Can anyone confirm this if you have SF4 + fightpad?
