The easiest way to learn to shoot well is by learning good repeatable form but some people are naturals when it comes to being accurate. Check out the short vids of some of the archery greats...Fred Bear, Ben Pearson, Stacy Groscup, Sterling Harrell, etc. They weren't exactly picture-perfect with their form yet could shoot lights out consistently. Alot of one's results comes from the mental side...sight picture, natural 'feel', confidence in what looks/feels right, etc. But adding some insurance in the way of good alignment, repeatable anchor point, smooth release, etc., sure can't hurt for most of us mortals.
