This is compared to regular moves that have only 11. The deal is that the AI does not take advantage of the extra frames, but human players do. Here is a video showing a 1 vs 1 match where the enhanced wake up gets hit on the 20th frame of the attack and yet it nullifies the projectile. It is actually in versus mode, just having the infinite meter code on and the timer off.
Thanks to Playpal for pointing it out.
