I think you make a good point. I usually practice from the ground, just to work on my release, etc. However, the buck I shot this year was from a treestand. I managed to keep it together, had the buck sighted in at only about 15 yards or so, a nice quartering away shot. Right before I let the arrow go, I told myself, "Aim low." So I aimed at where I figured the heart was-- way low-- and let the arrow fly. I tried to bend at the waist, but in the heat of the moment, it's hard to remember exactly what happened. Anyway, when I recovered the deer, I was shocked how high the arrow hit! I was actually afraid that I might miss the deer low because of how I was aiming, but it ended up punching through both lungs. You can bet I'll be practicing from an elevated position this summer!
