Go by the ketostix. If you are in ketosis that night (night of your workout) then all is well. If you are not, then you are taking in too many carbs (e.g. cut out the PWO carbs)
You want to refill muscle glycogen. After stores are full, you runneth over into the stomach and ass (so to speak). Like you said, if your workouts are intense (ie depleting glycogen) then things are good.
I'm doing a TKD right now so i know exactly what you're after. Good luck bro.
