I have noticed that when people try to adapt the Hill shooting style via the Schulz videos and then adding some other influences, that when they think that they need to draw and release fast that the anchor point is neglected or not consistent. If one looks at Hill when in his videos when he was shooting at still targets, there was most definitely a solid anchor. The short time needed to be at that anchor was a product of years of doing the same thing over and over. As Hill advocated, do each part of the form slowly and GRADUALLY pick up speed. As far as his split vision aiming, according to Schulz, Hill did not specifically teach it to him. However, with good consistent form, I think what Hill describes is what your on board computer will do for you, he simply breaks it down to the details, because he does say that one caannot get too dogmatic about aiming and that, after time, it can be done faster than instinctive shooting, sort of a second nature..
