I have to agree with the guys above, I myself have been doing a lot of experimentation and I’m having a ton of fun.
Don’t forget, you can also buffer super/ultra from back dash/forward dash. I find that this is highly underrated, but Vangief makes awesome use of it. I’ve seen him face an Abel, force Abel to whiff U2, back down and land the ultra. Though Gief’s slow ass dash is better used against attacks with heavy start-up/recovery.
st.lp/st.mp can also buffer it relatively easy. For me, it’s a bit similar to the charging concept. You’ve got some limits, but a variety of ways to get the move out from certain situations. Try baiting your opponent too.
