I completely understand your struggles. I know if I keep throwing arrows to the left that it is because I don't have a solid bow arm. Its not usually bad maybe 2-3inches left but its enough that is could case a good shot to become a bad shot. I know if my bow arm is bent too much It will be a problem for me. I almost have to have my elbow locked, almost but not quite locked. And then if I compound that with over-drawing I can really throw the arrows wide. Trust me it can get ugly sometimes. LOL[:'(] So basically what im saying is I beleive the bow arm plays a HUGE part in accuracy.
