Kt, I think that the level of compensation depends upon how close the deer is to you. Once you're over 12' or so and the deer get in close, you don't have a lot of "body" to shoot at. It's very easy at even 15 or 18' to not be shooting at the ground under the deer instead of at the deer itself. The higher up, the worse the angle.

Don't worry about practicing 20' up, practice at your target CLOSE! If the deer is 5 steps from your tree and you hold your 20yard pin right where you want to hit, the arrow is going to strike low....why? Because the arrow has yet to reach the line of sight height that close. On a shot that close, use your 40 yard pin....(I'M NOT PULLING YOUR LEG HERE) When you get a minute stand 5 steps in front of your target and shoot a small dot with your 20 yard pin, then shoot at the same dot with your 40 and you'll see what I mean.

All of this compounds on an accute angle shot and you'll most often shoot right under the deer. Don't worry about missing, that in my opinion is the toughest shot in bow hunting. (personal experience speaking lol)
