There's a variety of "Quiet Eye" videos using laser optical measuring equipment to make the case that the accuracy of hitting an intended target will increase through the practice of slowing down eye movement and focusing on the target with little or no eye motion just prior to shooting. The videos range in scope but do include pistol shooting and putting in golf. I have been trying to relate these in perspective to pool and since I taught the OB must be the last thing looked at before shooting, I believed it wouldn't be a stretch to incorporate some of the information stated in the studies, in an effort to better my game. What is an average time lapse between the last look at an OB and contact of CB ?
