Good post. There were a couple of shows about jumping the string on the hunting channels. If you slow motion video the deer's reaction to the noise of the archery shot, they crouch just before leaping, just like we would do if we were going up for a rebound in basketball. This is how they always respond when they are suddenly frightened. The chest/body moves south and the arrow ends up over the back.
At ten yards, you may have made a bad shot or alerted the deer with your movement - the deer's reactions are not that good to dodge an arrow at that range (I think). Farther out, the "experts" suggest aiming a few inches low in the expectation that the deer will crouch as the shot is made. Many times, this could result in a miss too, if the deer doesn't hear the string.
Better luck next time JP.
