Have you tried grabbing the stringjust back of the pads of your fingertips instead of deep hooking and burying it in the creases? That'll bring the nock over to the left a bit. Maybe a big bit.

I've had some problems with left misses that I couldn't explain and had a few people watch me shoot. They tell me thatmy fingers don't straighten out when I use a deep hook and bend that those fingertip joints. That's the 'cupped hand' Asbell shows in his book.

Rather than move my anchor over to the left to compensate, I just went back to using the fingertip grab instead of the deep hook.
