... So I watched Shijinkydinks advance frame data tutorial and idk if I am calculating this right

He said you have to subtract the cancel advantage frames with the active frames and take the answer, subtract it with the start up of the special move.

So Jades first move in Edenian Rush, F3 has 2 Active frames and 18 cancel advantage

18-2=16 frames

Edenian Spark (DB3) is 20 start up

So 20-16=4 overall frames . F3+DB3 special cancel is 4 frames. Is this right?
