On most characters when i do this combo in the corner i usuky jump back for the first jD than just when the oppeenet is below millia weight (in the air ofcourse) i do the AD than i do a little pause and than jK jD with a light slight pause between the K and the D than again waiting for the oppenet to drop a bit more and again AD a little pause and than jD on some chars i jump and delay the first jD (like Testa) and for some chars i jump straight up for the first jD (aba for example) and some well i prefer doing other combos
but its kinda hard to explain in a forum posts cause ppl usuly got diffrent timing on thier delays
but i hope this somehow helps
