Wow, Bob! I'm a little embarrassed that I'm suggesting to others that they read your articles, and I somehow missed this. I'm also stunned that I used such a similar setup. Maybe I did read this article at some point in the past and it was buried in my subconscious. I apologize that I didn't acknowledge it. I'll go and add a link in the YouTube video description.
Hopefully the video at least renews interest in the subject and offers a slightly different "moving-picture" version of your experiment. It also offers slightly different results, although a lot turns out to be very similar.
Maybe conditions are a factor? I used the Aramith Tournament (Duramith) Balls. Do you recall what balls you used?
I'm about to embark on another experiment to show minimum throw using the golf tee guards on my RotoThroTractor and Gauntlet tools. Did you ever test for minimum throw, and if so, how did you set it up?
I'm not looking to repeat tests that were already done. I actually want to get back to preparing and sharing the system that began this whole journey, but I figure finding minimum throw is a worthwhile task. And for the sake of completeness, a minimum throw video would complement the maximum throw video.
Thanks again for all of your contributions over the years!
Below is a plot I made a long time ago about throw versus speed and angle. It was included in my June, 1995 Billiards Digest article which you can find here:

I think you will find a lot of additional info on Dr. Dave's website along with the theory that explains the very strange shape of the curves and the speed dependence.
