Interesting as heck. Do you know if the 11/16” quoted is the distance around the circumference of the sphere (where the CB touches the cloth) to where the cue touches the CB, or measured from the cloth directly below the CB contact point?If you look at this study you can see that the pros hit all their draw shots with almost the same contact height on the cue ball. I think that by just hitting a ton of draw shots you will find this spot intuitively. The spot is 17.4 mm (11/16inch) from the cloth.
