I go by feel and I visually look to see where my hand is compared to the riser. I roll my fingers into my hand and put my knuckles at a 45 degree angle when I set my grip. Then when I draw I let them relax and fall where they want.

I am seriously thinking of drawing a line on my girlfriends bow and hand so she can consistantly line it up. At least until she gets a feel for it. She has the same problem with her stance. She keeps wanting to put her back foot to the left of her front and shift her weight to the back leg.
