Stat I think it is an over tweaking issue.

I think you have messed with your setup and style so much you have "forgotten" how to shoot. I did the exact same thing5 years ago. I started messing with my DL and back tension releases. I got worst as a shooter. I went from the #1 indoor shooter at our club to not even in the top ten.

2 years ago I went back to my scott release and draw length I have had since I was 16. Slowly but surelyI am coming back to form.

Good luck.
