If I may, I will tell what we had in the yard a couple of years ago. A friend with a longbow shot either high or low on three deer in a week with a 68" longbow. He claimed his bow was too long to shoot down at the trail the deer were using. He was offered the ladder stand in the back yard for practice. A safety harness with the snap strap was provided and adjusted. Then the funny part, a 5 gallon plastic farm bucket with a folded piece of carpet in the bottom and a piece of cardboard taped over the top. He was given a bag of steel slingshot ammo and a wrist rocket. After a while he got pretty good with it, was not missing the angled bucket. Then he tried his longbow and had no problems at all hitting the deer target. He said, "What changed?" It was the safety harness. He was told to trust the strap going to the tree and lean against it, he did. He leaned into the shot. When asked if he had his safety harness on his hunting stand adjusted the same, he said that he could not get his around the trunk so he just tied it off on a branch. He was not leaning into his shot and not canting his bow.
