Well, there's only one time that you move your arm and that's during the stroke, so there are some body mechanics involved there that are independent from other fundamentals of pool. I've read your comments on why you feel the stroke shouldn't be considered a fundamental. There are some inconsistencies in your argument which is usually a sign of not having thought things through entirely. Figuring things out as you go along is fine and while you're doing that, I hope that you will also look at the other side of this. I think I've made some legitmate and logical points as to why I am sure that the stroke is indeed a fundamental of the game, just like the arm swings are in tennis and golf.
I've thought it out quite well, looking at how we learn skills, all sorts of skills, from the foundational core (defined as "fundamentals") to the performance of the skill, which is the result of learning those fundamentals.
You seem to be focusing on the stroke itself, not the final delivery of the cue. In that regard, the stroke itself is part of the fundamental process involved in delivering that final stroke.
We can't say every skill we learn or work on is a fundamental. Fundamentals are typically at considered the roots of the process, not the finished or polished product.
