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.

So here is another way to look at the Trick PIn data and compare it to MPBR (or as single pin pointed at the bullseye). In the previous post I listed which "pin" on my sight was on the bullseye as I varied the distance from the target with my 50 yd pin always 12" below the bullseye. I have stated I can use Trick Pin from about 13 to 43 yards and keep the my arrow roughly 3-4" above or below the bullseye, so the median distance for me would be 33 yards. Below is a comparison on the aiming error using Trick Pin vs holding a 33 yard pin on the bullseye from 10-45 yards. Is there any wonder that Trick Pin gives you a vastly greater kill range than any single pin pointed at the bullseye? Trick Pin is not MPBR, and why does it work? - because you are raising the bow higher as you increase distance from the target which counteracts the fall of the arrow. Period.
