My first several shots were fine. Arrow flew well to the target. About midway through my practice I noticed my arrows would go hard left it seemed just before it hit the target. It was very noticeable. I don't know if that has anything to do with form or grip of the string. Brace was set at 7.5 like bowyer said. Never seen it do this before. It almost looked like the arrow did a loop d loop about 1-2 ft before the target. Anyone have any ideas? Weak spine? just bad form? Strange that it would happen after several great shot sequences. I don't recall changing of anchor, but that could be.
