I always enjoy reading Arne's critiques of people shooting, because he does such a great job of it. Coming to full draw should help your accuracy because you can establish a consistent draw length, and also because it will get your elbow behind the arrow, which helps prevent right/left errors.
However, it will also increase the pounds you are pulling, and therefore it becomes even more important to make sure your arrow is within the weight range specified by the bowyer, as we were discussing in a different string of posts.
