What moves are considered Technical and Reversal in Street Fighter 4?
What do they mean?
There are two moves that are called "technical" by the engine: throw defense (LP+LK when your opponent tries to throw you) and quick stand (down when you are knocked down).
Reversals are related to timing. A reversal is a special move done at the first frame of recovery (after a knockdown, block stun or hit stun). In example, if you do a Shoryuken right after get up from a knockdown, it will count as a reversal.
