Great shooting Rod. I hope to hit a 60 before this is all over. As for tips, I know this has been said a million times, but you just have to do everything the same every time. I always have a shoot routine that I use for each arrow.
1.Establish stance (shoulder toward the target, feet shoulder with apart, back foot slightly back).
2.Nock arrow, grasp string in the first groove.
3.Focus on target
4.Inhale slowly and exhale slowly
5.Inhale while drawing to anchor, with natural pause on inhale, use a three point anchor middle finger corner of the mouth, cock feather on the tip of the nose, and thumb tucked behind the jawbone.
6.Pause at anchor, increase back tension while focusing on the target, and let the release happen.
7.Hold focus and bow arm on the target until the arrow hits.
8.Exhale, relax, and prepare for the next shot.
Always make every shot count (shoot it like it was the only shot)
When practicing I don't shoot a lot of groups I only shoot one arrow at a time and go get it.
Once you have established your form, you can concentrate on repeating it each and every time. It is all about consistency.
Enjoy the shot
