I have one pin on my xbow. At 20 - 30 I put it at the bottom of the heart on my target. At 30-40 I put it dead center on the heart. I choose not to shoot past 40. 2 - 3" (at most) difference in aming yields the same results moving between 30 and 40 yards. A deers heart is about the size of your fist. If you have a compound that will consistently shoot an arrow with less drop than half your fist between 30 - 40 yards, using the same pin and aiming at the same spot on a target or deer, come show me, bring your reciept, and I will buy the bow from you at double what you paid for it.
