Must be karma because I looked at his system last night on youtube. He uses slices of the cue ball aimed at the center or edge of the OB. It gives his system 8-9 spots to aim with. Now of course it's TOI.
The systems don't have any 'granularity' to them. You estimate the points as accurately as possible, just as in contact point systems.
LAMas has a pivoting contact point system on here too. This is similar but you don't need to find the CPs. The points on the edge work just as well if not better.
Once you see the equal areas the process can be quite good for working the last quarter of the ball. Back cuts are much easier to gauge and aim with these overlap methods.
