It's not a DP (SRK) motion whatsoever. Not sure why everyone is telling others that. The only one that's a DP motion is the Gen Fu that comes after it. The EWGF idea for that is hitting 6 and then immediately 3P - 6[3P]. at the same time (Similar to Eliot's 46P mid strike where you do 4 and then [6P] at the same exact time . No motion, only do the motion if you want the Gen Fu strike.
when i do dp motion, i get the 236p command, but this game is super lienient with the inputs, so i can see it reading 623 as 236, anywayz, gonna go try out D bombs method when i get home, gonna be egwf'ing with the best of em
