How is this Evade Possible?

Explanation:

Sarah's K+G is a full circular high that forces sideturn on normal and counter hit. On counter hit, she is at +9 advantage and her opponent is sideturned. Because it takes 3 frames for the opponent to face Sarah again before he can evade or guard, Sarah is at +12 advantage. Sarah's 12f linear high punch should hit the opponent if he does anything other than crouch (crouching does not require you to face your opponent, so there is no 3f penalty).

Question:

Why does this setup work on the CPU when set to "Defensive Move 1" (evade to the background), but not "Defensive Move 2" (evade to the foreground)? How does the CPU have the frames to evade the punch?

 

The direction of the roundhouse gives a few frames of leeway if you are evading toward or away

 

This was my first thought as well. However, if I switch stance for Sarah (P+K+G) the results remain the same. DM1 cannot evade, but DM2 can.

Sarah has other side setups as well. If I can hit my opponent with 3PK from the side, Sarah has +8 advantage, meaning 11f attacks should land. Her FL P and FL K are 11 frames. Same results, DM1 cannot evade, DM2 can.

Yes, I can do it too. Though my success rate is quite low. Maybe 1 out of every 20 tries.

Is it possible to crouch and evade the same move? If so, then the entire idea of nitaku would be invalid, right? If I can duck a throw and evade an elbow at the same time. Or is there some hidden tech that I don't know about. ETC = Evading Throw Crouch

 

You can do that in Virtua Fighter 4 Evolution. Sometimes I get it by accident.
