Don't go worrying about some mythical standard you should adhere to before going hunting. There is a distance you are comfortable with, right now. That is the distance where you are absolutely confident you can hit where you aim. Whether that's 5 yards or 30 yards, keep your shots within your confidence zone and go hunting.

Then, during the off season, shoot 3D's and practice. There is always room for improvement, and improvement doesn't come when the bow is gathering dust and cobwebs in the back of the closet.
