My form was pretty bad for a long time, but I still shot reasonable groups. A lot of what I brought into archery was from firearms training in the military: Focus on the front sight, lean into the target and breath control. One day I tried something different: I focused on the target instead of myself and the sights. Instantly my form got better and more stable, the sights seemed to automatically come into alignment with the target, and my group size went way down.
