SSF4 Counter hit questions

Hey, I’'ve been having a problem landing certain combos when they counter hit. I play Chun-li and I can do her st.lp into st.fp with ease but if my st.lp hits on a counterhit (as opposed to just a normal or blocked hit) i can’t get the st.fp to come out. I know you gain some extra frames on counter hits but I just cant seem to get this down. Is my timing just off or do counter hits just make certain combos not possible?


Are you getting the st.fp to come out during matches or during training mode?
