[Yoda]

What I am asking is an answer in degrees...

Fortunately, Jerry, you will find no such answer in The Golfing Machine.

Homer Kelley's Star System of Golf provides practical aid for Golfers where they need it most: On the Golf Course. He had no interest in laboratory measurements, although he stated that the lab would show those he defined to be "well within acceptable tolerances" (1-H). Further, in the three Golf Stroke Engineering Master classes he lived to conduct, he was openly skeptical of any golfer being able to see -- much less achieve in actual play -- "eight degrees" of this or that. The whole thing just happens too fast and varies from Golfer to Golfer and Stroke to Stroke.

Accordingly, he was interested in defining relationships only in terms that can be checked visually (and thus be reliably applied). These include, for example, "flat, parallel, horizontal, vertical, straight, On Plane or centered" because there is "no question of degree in such alignments" (1-C). So, other than the application of Normal Force -- at right angles (90 degrees) -- Component Relationships are defined in terms of a geometric figure, not in terms of degrees.

Given the already daunting nature of the book, consider it one of Homer's 'tender mercies.'
