As someone who hadn't played fighting games in a long long time and jumped into Street Fighter 6 ... it's very helpful to see something that explains what these numbers are.
I've played anime games (mbac way back when and strive) before so I'm no stranger to the system, so I'm glad sf players are starting to adopt it. I still see a lot of people notate with st.MP or cr.LK, etc. but specials are mostly numpad notation or the move name now. Honestly surprised sf community is trending toward numpad notation.
