Mutation Series - Quick Question

In CT’s mutation series, when he says:

3 sets of 5 reps
301 tempo
No rest

does this mean the same thing as 15 reps straight through?

I am confused because he gives no rest times in between sets. I realize it is no rest from one exercise to the next, but I just wasn’t sure how to handle it from set to set of the same exercise. Any feedback is appreciated, thanks…

I think he used a modified OVT. The sets should be arranged A1-A2, B1-B2, etc. There is no rest between A1 and A2 - they are supersets. You will rest after A2 each time, but you go directly from A1 to A2 with no rest.

I could be wrong, as I am going from memory - so consider the source.
