Walk forward CR.JAB

What is the frame gap when you do CR.JAB > walk forward > CR.JAB perfectly?
Is it 2 frames or 1?

startup of cr.lp is 3 frames(active on the 3rd) and is +4 on block.

so it depends how long do you want to walk forward for? you can walk forward for 1 frame and have a true block string.

walk for 2 frames and have a 1 frame gap.
walk for 3 frames and have a 2 frame gap.
and so on…

does that answer it?
Can I ask why you want to know?

thanks, that answers it
i wanted to know this for frametrapping
