So I was thinking there must be another way to demonstrate that the "Trick" to this method is that by holding on a point BELOW the intended POI, in effect the bow is constantly being raised as one backs further from the target, which offsets the natural drop of the arrow. I held my 50 at a point 12" below the bullseye at the following distances and noted which sight pin was actually on the bullseye, or interpolated between pins. This makes it clear: Distance of 10 yds - 7 yd pin, 13 yards - 11 yard pin, 15 yards - 19 yd pin, 20 yards - 23 yd pin, 25 yds - 27 yd pin, 30 yds - 32 yd pin, 35 yds - 37 yd pin, 40 yds - 39 yd pin, 43 yds - 40 yd pin, 45 yds 41 yd pin.
So to recap I go from a 7 yd hold to a 41 yd hold as I step back from 10 to 45 yards using Trick Pin. THIS solely is why trick pin allows such a long window for kill shots with a single "aiming point". THIS IS IN NO WAY related to simple MPBR because initial ascent angle of the arrow (bow angle) is NOT BEING HELD CONSTANT.
