I will show you...
If you actually land the auto GI from AG (catches lows), such as after blocked 4(B), 4 (your auto GI catches their 2A for example), the stun is really long. You should then press 6 to go into prep, then 2 for shadow evade, and B for the good stun. There's plenty of time to do this. So basically, low auto GI going into AG, 62B.
