Didn't really test much, all I know is that it works more consistently the closer you are to Ivy. Tried stepping to the other side, but in my limited testing it didn't work.
8WRing however worked when holding 9 or 3 depending on direction after 6B+K, and you don't even have to jump. 2nd hit will whiff automatically
You can punish with at least an i28 (tested with 33B but didn't record)
