I usually don't shoot groups either. I also don't shoot quantity shots, I go for the quality. Some people will go out and shoot several hundred shots, especially before season starts and that evidently works for them. I do shoot everyday, but lots of times it is only one shot. Rain, sleet or snow, I take the shot and go on. I also shoot with no hold time on the draw. I raise and draw the bow at the same time, and when I hit my anchor point, the arrow flys. My brother will hold his, sometimes for minutes at a time, till both hands are shaking so bad he looks like he needs a pill or something. The longer he holds, the worse the shot is. Stick to the style you are comfortable with because if you start changing styles, basically you are learning to shoot all over again.
