In general over the past 4+ decades of archery hunting from a tree stand of one sort of another, usually 15' - 25' off the ground, I have missed high. This is primarily due to the deer dropping, loading its legs to haul tail as soon as it hears the bow fire. I have long ago "trained' myself to intentionally aim "small", and somewhat low ... but not ever out of the "kill zone". The newer bow designs that create arrow launch velocities around 300 fps +/- have mitigateed to some degree the issue of deer "jumping" the string. I have no clue what velocity that my first hunting bow did. It was a realitively inexpensive fiberglasss Ben Pearson stick. My second was a fine recurve that cost me a whopping $45 in 1966. It was a vastly faster bow than my old Pearson. The most recent bow that I was using, before the shoulder injury, was a Matthews SQ-2. I found it so fast, that I was easily able to shoot from right under my stand to about 30 yards with one pin .... adjusting elevation only very little from 15-25 yards. I did add a second pin for 40+ yards.
