Nah, usually never after a knockdown as my brother habitually wakes-up EX devil reverse. I've learned to stop jumping at people almost completely and have REALLY worked on my pokes. That being said, theres usually that time during the round where your opponent is just outside of your range, or in this case, Ryu's cr. mk, and you're just outside of the range of his s.mk/s.hk. there are times when ill step forward to immediate cr.mk to get in his range and push him back again, and theres other times when I'll neutral jump after entering his range to make sure he stands back up again from a crouch block. He if doesn't, thats an obvious combo, if he blocks, you usually get a decent amount of block advantage and can go into a mix up. I've learned with most people online, unless I'm Rufus, I have better results with just letting them stand up and consistently push them to the corner where I will remain patient and wait for an opening. Obviously on those pressing rounds where time is a factor and you have a health disadvantage, you are rewarded with those kind of luxuries, but I've found that adopting this sort of play style has taken my win percentage much higher. I think im about 78% right now, which is pretty good for me.
My execution with certain moves is still kinda balls, but from working on my plinking, I have been able to nail a cr. lp to cr.mk much more consistently as opposed to it not combo'n.
I was pretty upset I missed a cr. mk, to EX tatsu to ultra yesterday and lost because of it. I friggin double tapped the ultra and it came out about 3 frames too late. I don't remember ever doing that before and lost the round because of it. I did go on to win the match, but it was from the aforementioned strategy that helped me keep my composure.
I have noticed with Ryu I tend to NEVER EX anything anymore. Don't ask me why as EX tatsu does an ass load of damage. I will say I shory'd into super about 4 times on my brother and hadn't wasted it once
