Alright, here are my conclusions. Using Sektor's enhanced teleport uppercut, it has extra invincibility in vs. mode. At least 19 frames. The other enhanced move I tested was Mileena's roll and it had at least a few more. To me, it always looked like enhanced moves had more invincibility when I saw matches, but I guess NRS somehow made the cpu fail to take advantage of it. I removed the wake up attack part in the post until I can figure out specifics. Hopefully this is the only thing I'll have to test in versus. :\
