if I am reading your post correctly, I am seeing that you can dial it in but the first shot may not be right on. Thinking about how we hunt, we need to really worry about that first shot.... not so much the next several. Although shooting groups is a good thing, the fact is, you are likely to get only one shot.
Stump shooting... loosing only one arrow per target, at unknown distances, is a great way to work on that. And, as told above... shooting before you go out into the woods, or better yet, as you are hunting will help you dial in. That first shot, however is THE ONE.
