"Mere child's play."
Basically, I'm doing roughly the same timing/spacing for the dash and jump in (though you can vary this and change the results) but vary the timing on when I press the 1. This is similar to how Adon's jump in mixups work in AE.
Not sure how this varies from character to character and wakeups will surely weaken this setup but I thought I'd post it anyway.
