Pulling on your left thumbkin may prove helpful. If you feel as though you are pulling on plane with the shaft as opposed to below plane, then you might want to look into how you are gripping the club with your left hand, seeings that this determines the degree of the #3 Acc. angle. If # 3 is zeroed out or close to zeroed out because you are gripping too much in the palm the pull will be close to or actually on the plane of the shaft. The idea that golf is a game of inches is quite apparent when you consider the # Acc. I like to look in the mirror to visually ensure that the stretch is below plane.
