Longstick, I hope this will help you as it did me. About 5 months ago I decided to change my anchor from my middle finger to corner of mouth to index finger. When I did this I knew I was going to be a little high but it would correct itself after awhile, however it did not seem to be doing that and was getting worse. I had 4" groups of holes, shot 1 at at a time, approx. 5" above target. A friend of mine had done some videos of me when I had problems releasing using my old anchor and offered to mke one of me shooting the new way and to break it down to frame by frame. What we found, when comparing frames, is because of the sight relationship I had ingrained with my old way( anchor,arrow,target) I was leaning my head slightly forward with the new anchor which caused the high shots to go even higher.I worked on changing this and am quite pleased to say everything is otay spanky.
