I've been applying the three suggestions that Arne gave me after viewing a video of my shooting:
1.--keep my head up above my shoulders---don't move it---draw that string to it. I have discontinued the use of feather to nose as in my case I would seek it out with my nose changing my head position.
2.---open my stance---once I applied these two things I found THE LINE that is always talked about. My lefts and rights are no longer an issue. When I do my part these are taken care of.
3.---Practice the above until you have it and then make it yours.
I have been practicing all winter at 15 yards in the pole barn. Once form changes were solid I focused on an aiming technique that would work for me. With limited vision in my right eye I shoot left handed. With virtually no depth perception this adds to the challenge. I shot at paper targets, 2 inch squares, golf tees and would get irritated if my arrow was 4 inches outside of the mark.
This past weekend I went to a for fun only 3D shoot and applied what I had been doing. The first thing I noticed was how I didn't have to think about my stance or my head position or my anchor---they were just there for me and it just worked. The second thing I noticed was that my killzone accuracy had sky rocketed. Both days I shot a 490 out of a possible 600. This may not sound like a big deal to others more accomplished, but to me it is a huge improvement. The final thing I noticed was that I was confident on each shot, knowing where I was going to place the arrow tip each time I aimed, and that I was having fun.
My thanks to Arne for the time that you took to give me feedback.
