This may seem counter-intuitive, but when I just "let go" and don't even think about the shot, I seem to do better than when i "concentrate" on making a "perfect shot". In fact, it seems that the best shots I have ever made were done during a timed shoot -- 30 seconds, as many arrows as possible (accurately) -- I didn't have time to think about where my anchor was, where the arrow was pointing, how far back my elbow was, etc.
Just shoot, don't think about it, and see what results you end up with. It's worth a try, at least.
