Shit, I did contradict myself there.
-Min bar speed for an @10 effort varies by rep count. x1@10 min bar speed will be higher than x5@10 min bar speed. [Mike T has said this (
one instance here), and it's also been true in my training. I think the slowest squat single I've recorded is .17 while the slowest @10 multi-rep set was .14 (x3 or x5, I don't remember)]
-If you're going into a session with high fatigue, the min bar speed will be higher with larger drop offs in bar speed towards the end of a hard set compared to the same rep/RPE set while fresh. I guess this is more related to technical RPE than anything... back rounding to a degree that's unsafe.
