I've been IBing and spending almost all of my meter on CAs. It is kind of sad.
. All of the mods worked hard to put up the frame data for CP. You could at least have checked it out before making claims about frame data. And like the wiki says, Dia 623C has Head invul from frame 4 through 19. Not really a valid wake-up option in most cases but since you managed to make 4B into a reversal in Extend, you will probably be able to make it work after some practice.
