It depends on the speed of the platform crew. Observe the flight before yours if possible and clock the speed of the crew to change weight and adjust the rack. Then compare your speed of wrapping to your result. Be careful during third attempts because you get lifters failing, running the clock and passing, using more of their clock time, etc.
Finally, wraps don’t need to be pulled to the max. If you pull to max tightness you will not get the same bounce out of the hole. This way if you wrapped a tad early, your wont go numb.
