SF4 doesn't have a lot of complex individual moves. A better example in that game would be consistently doing a particular C.Viper combo, or nailing FADC>Ultra combos 100% of the time. Also a good illustration of how you don't always need the most complex things in a character, there are some crazy combo vids out for SF4, but a lot of it is things you'll never see in a match, even from the very best players.
