No problem. We don't need degrees.
Great. This is all we need.
Just put the cue ball on the head spot and the object ball a diamond downtable from it, then put balls on the foot and side rails where the thick, thin and thinner ranges begin and end. This should take you no time at all since you're so practiced at visualizing it. The Wei table below shows how it might look.
I just guessed and put divisions at 3/4- ball, 1/2-ball and 1/4-ball cuts, which only includes cuts up to a little over 45 degrees - your divisions might be different (maybe covering even thinner cuts?).

If you do just this much I can make my point clear without any more tests. Even if you can just tell us if the 3/4-ball, 1/2-ball and 1/4-ball cuts are roughly the right dividing lines, I can work with that.

I'd shoot this test with enthusiasm. But, like I said... only if you're gonna crawl outta your hole and do the test too. Post a video of you running through the paces and I'll reply with my second video.
