Stu,
I am selecting your post to question simply because I think you are one of the sharpest and most knowledgeable men in pool. I have tremendous respect for your knowledge. Now I will pick apart your post!(grin)
I. I would much prefer to face someone that constantly works with a half dozen systems than someone that only uses 1 or 1 to 3 systems and uses them well. Also, the person that works with many systems would be better off spending their time elsewhere in my opinion.
2. What does this gain over the same time gaining experience on the table?
3. What does knowing the physics gain over knowing how the balls move without being able to spell physics?
4. I beat every major player I have beaten using draw and a touch of side. I found something that worked and used it for years. With many thousands of repetitions in that break, it worked for me!
5. Here I won't agree or disagree. I don't know. I will grant your much greater experience and time witnessing top players in action.
Take a hard look and think about your first four points. Do any of them help a person play better on the table? Would they be better learning the "book smarts" of these things or putting in the same effort on the table?
I am going to invoke Efren as old school. I don't know what education he has, certainly very little formal education, no physics or advanced technical education. While he is an outlier simply by being the best in the world for many years until age took him down, during much of that time he worked with very poor vision. His knowledge and tuning on the table carried him through.
Going back to my own experience in various forms of competition, I studied the technology to seek an advantage, then got my ass kicked by men with twenty years or more of experience and not a fraction of my technical knowledge.
Remember when the Kenyans first came to the Olympics? No science or technology at all. They came and ran barefoot and kicked everybody's ass! A man in I think Australia ran a five day or week long race in workboots. The people in running uniforms and running shoes thought it was funny until when they stopped for the day he kept on running. He won.
Greater technology is valuable. I have played enough with carbon fiber to endorse it simply because it plays the same whichever way I turn it while the best wood I have played with benefits, if only a tiny amount, from indexing. The question is would developing a CF shaft themselves have been a more beneficial use of the competitor's time than hitting balls for an individual competitor?
If I can use one technique and accomplish all of my goals for a shot, does it benefit me to know six more ways of achieving the same result?
Has a pool player ever played better because they had a degree in physics? In another arena, bullets shot from some rifle barrels cut the wind better than those shot from other barrels. When I was competing twenty years ago the world record for five 5 shot groups at one hundred yards was 0.150" Shot by a man I was proud to call friend, Jef Fowler.
Countless thousands of tiny groups shot, yet nobody had a definitive answer as to why some barrels cut wind better. The components are the same, got to be something unique in the metallurgy or machinery of the barrel. After decades of searching and even using an electron Microscope, it was still an unknown. A man with very impressive scientific credentials sent me a PM asking why I was giving respect to people with little education that had owned such barrels in a thread and asking follow-up questions. Eventually I owned such a barrel. It was made and machined at the same time as barrels that didn't cut the wind as well. I know no more about why now than I did when I first discovered the abilities of that barrel thirty years ago.
Could the same thing exist with some cues, or other components? Could some cues, shafts, or tips, send a cue ball across the cloth with less interference? Science may find such a thing and chances are the discovery will be by someone that can't run five balls!
I wrote a book but the question is what is productive effort for a competitor and what is merely gilding the lily for the competitor?
Side story here, derailing my derailment! I was a Master CNE. To obtain that certification required passing a dozen tough tests. I learned that cramming doesn't work for me. I might spend five or ten minutes looking at one thing but usually not even that long. Driving the thirty minutes to the testing center, I listened to country music. Intuitively I thought Marty or Merle or even Mel might give the best results to ready me for testing. Johnny Cash produced the best scores. I thought it was a rabbit's foot but before a very tough test I listened to Cash!
