Can we please quit the wordsmith wars & someone offer conclusive evidence that the pendulum stroke, particularly the finish is better than that of the 'piston' J -stroke. Better... & not because it is more simple & easier to teach, but better.
Now this is hilarious! *You*, the "grasper" of analogies (and analogies that poorly support your case, no less), are complaining about wordsmithing? A definite case of the pot and kettle...
And, sadly, RJ, all this time while you continue to harp on pendulum vs J-stroke, we *have* been explaining to you the reason why instructors teach pendulum and not the J-stroke. But you keep ignoring it, pushing it aside, and focusing on silly analogies and semantics like what kind of movement do today's projectiles use vs. devices of the past, and what kind of movement does the human body use to hurl very heavy rocks -- all of which have bupkus to do with propelling a cue that is suspended from an arm positioned over it. And your bow/arrow analogy? Also bupkus -- for the same reason: the arm is not a string that is equally spaced on both sides of the cue as a bow is. And the human arm -- which flexes on joints -- resembles a taught string in no way, shape, or form. So please don't "grasp" at analogies with devices that in no way resemble the form and motion of the human arm.
The thing you keep glossing over (or conveniently pushing aside), the reason for why simplicity is important, is repeatability. The instructor teaches a simple, repeatable movement, because it is 1.) less moving parts; 2.) easy to produce; 3.) easy to troubleshoot and diagnose problems with. All of these are important to someone who is having problems with consistency or otherwise may've reached a plateau and hasn't figured out why. This is as opposed to teaching a movement that is complex, not easy to produce, and not easy to diagnose problems with.
And, you're making it out like if the instructors "see" you using a J-stroke or whatever, that they're going to rip you down and replace your movements with this cookie-cutter pendulum template. That doesn't happen -- the instructors build upon what the student already has. Only in severe cases, where the student is clearly wrestling with the movements of his/her stroke, will the instructor suggest the pendulum. They (all the instructors) state that.
But you conveniently ignore or push that aside, as if you don't want to hear that, do you? So instead, here you go, arguing these platonic / altruistic ideas you have about the J-stroke (as if you think people are calling your "baby" "ugly" when they're not), and ignoring the pragmatic part of the equation.
Look, I feel I more than adequately addressed all your points about why the pendulum stroke is taught, and I even pointed out why your analogies poorly support your position. So I feel I said my piece, and I'm not going to continue going back and forth with you, pointing out something that you keep pushing aside. You either get it, or you don't. I'm fine, either way.
Hasta,
