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°

AtLarge...
What I meant by linear was the horizontal line bisected by the 5 vertical aim lines.
I didn't mean the cut angles increase linearly. If vertical lines follow the contour of
the ball they wouldn't be equally spaced.. (like longitudinal lines on a world globe)
and would be increasing narrower from center to edge. Think of a flat disk instead
of a sphere, with evenly spaced lines,
or 5 vertical aim points on a pencil glued to
the front of the OB. CCB aim at the 5 points would be OB overlaps center to edge.
I know 1/4 ball isn't exactly 15*.. If someone put both arms up, one at 15* and the
other at 14.5*, I doubt if I could tell... 0, 15 & 30 are just easy to remember.
IMO
Thanks for 1/8 ball overlap angles increasing wider than 8 degrees after 30*.. Carl
