Guy's EX Tatsu is broken in USFIV. 2f, and cancelling into run-stop leaves you at -1f if you do it perfectly. That's better than safe DP FADC because the latter requires 2 bars and leaves you at -2f in the AE, and -5f in USFIV. Guy can also do EX Tatsu kara cancel into Bushin Flip to escape the corner now if the opponent gets to close on wake up.
