What is the dispersion of cue ball locations if we consider contact accuracy to be within a 32nd of an inch, a sixteenth total? The dispersion from either side of centerline is minimal. The dispersion from the outside of the contact area when considering starting off from one side is more, considerably more if we add in that many pro's advocate some level of sidespin to almost all shots.
Just the nature of two curved objects, the further from center the two objects contact each other, the greater the effect of the curves. Moving where the contact area will be from a less sensitive area to a more sensitive area seems basically flawed.
