IMO the ball overlaps can be more precisely found.

No math involved.. Just knowing your aim point for
Center CB.. You'll only need to know the pocketing
angle that the OB will go if the CB hits at that point.

If center CB is aimed at center OB ( line 1) it goes straight.
If center CB is aimed at the OB edge (line 5) ....it goes 30*
If center CB aims 1/2 way between 1&5 (line 3) it goes 15*
Whatever OB line is aimed at, it can be seen & will repeat.

The cut angles do not increase linearly as the overlap decreases, but your approximation of 7.5 per eighth of overlap works fine out to the half-ball aim.

Here are the cut angles to a little more precision for each eighth of overlap or fullness. It's important to note that these cut angles ignore throw.

Overlap (Fullness) -- Cut Angle
  • 1 (straight on) -- 0
    7/8 -- 7.2
    3/4 -- 14.5
    5/8 -- 22.0
    1/2 -- 30
    3/8 -- 38.7
    1/4 -- 48.6
    1/8 -- 61
    0 -- 90
