The biggest aid in accuracy for me is lining up into my shot.
In other words, walking towards my shot - not straight.
I drift 3 right. Always have, always will.
If I was playing straight up, knowing I lay the ball down 7 boards right of my left foot, I would have to line up my left foot 10 boards left of my target. (3 boards drift +7 boards laydown point). In order to keep my swing straight, if I'm swinging the ball right, I need to line up the appropriate number of boards left, and tilt my feet a little to walk into the shot. So... If I want to hit 12 at the arrows, with a laydown point at 18, I would line up at , with my feet tilted to go 3 more right (besides my drift). Target is release point is 18, +7 for the laydown point, +3 for my drift, + 1/2 the swing in boards (3) = 18+7+3+3.
Make sense?
