When something is +2 on block like 66B, it means that your opponent has 2 frames of animation LONGER of a stun that you do. Ever notice both players are 'recovering' after both blocking an attack and attacking? Thats what O'm refering to.Not 100% no
If a move is, say for example 18 frames of impact, it means that you could literally pause the game and see a frame-by-frame of the whole move. The game runs on 60 frames per second.
