Thought it might be helpful to explain why it's PV for Oly lifts. PV occurs at a pretty consistent point in Oly lifts (top of the 2nd pull). It doesn't matter "how" the athlete reaches PV, they just need to reach it. PV, essentially, detemines the time available for the athlete to catch the bar. MV would represent the MV for the entire lift; which can be misleading. Different athletes can use different strategies/techniques during the lift based on: specific coaching, injuries, anthropometrics, etc. SQ, BP, and DL have acceleration and deceleration phases that kind of cancel each other. Also, heavy reps are often "grinded". We see differences in MV @ 1RM between beginners and advanced lifters, with advanced lifters being slower @ their 1RM. Something like that would be lost in PV. Summary: PV for Oly lifts and MV for others.
