Focusing mentally first, and visually second on the spot you want to hit isthe appropriate way to be aiming according to everything I have ever been taught. Just an analagy.............
If you drive down the road trying to stay in the middle by looking at the yellow line in reference to your fender........you will dart all over trying to make micro adjustments to keep you straight. Now focus on the road 100-200 yards in front of you and allow yourself to subconsiously bring you to that point. It works much better and will allow you to maintain a MUCH straighter line.
Thisis why I am in the process of trying to develop very lightly tinted scope dots that allow you to stare through the dot at the X for target bow setups. I have a few already made but am trying to perfect the adhesive so it won't come off if you get outside in the rain. It is amazing how often you can hit the X on a vegas target when the dot/pin isn't even close to it when the bow goes off
if you focus consciously on the X. It just finds it's way there anyhow when you do this right.
As said by Mike Cooper..........
The eye follows the mind, and the arm follows the eye. Focus with your mind and the arrow will follow.
