RE: How much do you shoot?
Good practice a lot of arrows if it's bad practice (I miss) I stop shooting before I learn a bad habit. If I pick up a bad habit I go back to shooting at 5 yard and not trying aiming at anything and work on my form tell it feels good again. When you trying to aim hard some times a bad form sneaks in on you and if you keep shooting you are practicing it and it become a habit that hard to brake. When aiming hard at some thing you can't be thinking of other thing like your form. are your release it should come natural and when some thing wrong you can feel it at the shot and know what you done by the feel of the shot and correct it. If you can't don't practice it go back to form practice and don't think about aiming.
