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
