Thanks for this posting! I've just started back into archery, and I've been fighting my groups going left of my sight picture (I'm right handed / right eyed). I've always shot off my fingertips, and with this post in mind I specifically tried curling my fingers around the string more. Holy smokes, my groups snapped back to center. Tried it again off fingertips, grouped back to the left. Deeper hook, back to center. I'm amazed how much difference this makes. And both the draw and the release seem easier too. Now... why was this happening, since it never seemed to be a problem before? Who knows...
