Thanks for the tips, I can do this now. The minimum charge is important, but I figured that you have to focus on the dash timing. Wait until the shot recovers then dash, if you input it before the recovery, it won't come out. After you get the feel of the dash timing you have to learn to do the shortest dash possible and do 5CC as soon as you can. I still drop like 50% of this combo in online matches though... But I guess I should concentrate on other combos and confirms instead.
