I have been shooting indoor leagues for a few months now, and I am having a small problem. I start the round sighted in, on the X. Everything is fine (except user error) for the first 40 arrows or so. Then over the last 20 arrows, my sight is off about 1-2". My anchor point isn't changing, my sights aren't moving...not really sure the problem. Am I still getting string stretch, after all this time, and shooting?
Most likely you are starting to relax a bit. It's purely a focus thing. I've spent a significant amount of time on video working with my coach, and I've seen myself do the same thing. I don't change POI by 1-2" (more like 1/4"-1/2") but when I start to relax more things change in my form causing this.
My quess would be a form issue that starts to show as you start to get tired.Too much bend in the bow arm or shoulders being too open preventing you to get behind your shot can cause this when you get tired and start to lose a bit of focus. Also the way you execute your back tension or lack of back tension can cause issues.As RJ said,when you start to relax more,the shots will go off different.IMO,learning how to relax and execute relaxed shots is beneficial.
