Soviet Peaking Cycle

I plan on doing the soviet peaking cycle for squats. What would be the recommened rest period between sets?

I wait until I feel ready to do the next set, which is usually between 2 & 5 minutes.

What is your time under tension when doing this program? I’m assuming it would be under 20 seconds since it is to improve 1RM.

I’ve never timed the reps, but since I don’t do more than 5 & do them as explosively as possible, TUT is probably a less than 20sec.
