The IDEAL # to do, off of a focus attack, is 6. This is 850 stun which is one tortilla or slide or counterhit splash away from dizzy for most of the cast. 6 is hard to do consistently though. 4 is very realistic, offline I hardly ever fail to do 4 now and I am far from the execution master so it’s quite reasonable to expect. 4 does 750 stun so you’ll have to hit them twice more to stun. There’s little reason to do 5, it adds a small amount of damage and the extra stun(810) doesn’t really help much since you’ll still have to hit them twice more to stun them either way. This is assuming you landed a focus attack on an unstunned person. If you already have some stun put on them then you may want to stop it on 2 or 3.
So I recommend practicing 4 until you can do it like butter and once you are good at 4, start going for 6. If you ever get 99% accuracy on 6 then that’s better than me, that would be awesome though.
I use LP to run also, never gives me any problems. tap taptap tap taptap tap taptap. I think of it the same way as an above poster, like I am tapping out a rhythm on the table or a drum beat. Once you get the rhythm that’s all there is to it. Then it’s just about keeping the beat.
You guys that are still playing street fighter with pads really catch me off guard, it’s sort of like playing tennis with a hockey stick.
