I agree, this is impractical as hell, but it's possible. If you do something like 4B BE and have the opponent block it/or whiff, you can input 214:G during 4B BE's recovery frames. It comes out pretty consistent that way. Lol the second hit of the JF DC k combo is even possible XDBT DC is not possible to my knowledge. Whenever it occurs its either because of some glitchy camera turning, the air control of the opponent or if your opponent gets behind you while you enter DC. You cant just be in BT and then go into DC from there afaik.
Also you are wasting your time since this is 100% useless in a match. The only way to get it from time to time is if you sacrifice damage after 3B e.g by doing the 8A+B combo, then hope your opponents lands behind you while you automatically transistion into DC.
