Well, that's an exaggeration, Joey. I don't think cue sports have nearly the physical science demands that active sports like basketball do. I was getting more at the "standardized training doctrine" aspect, not hooking players up to monitoring equipment. I think you overextended your artistic license a bit to this one.
I would agree -- there definitely is a positive change afoot these days, in the toning-down of the mean-spirited comments. I would even agree -- to a point -- that your observation of naysayers backing off their "it doesn't work" claims. However, it could either be the groundswell otherwise is just too much to ignore, or it could be that people are just getting sick and tired of these threads.
I've always maintained my stance -- with challenge proposal shots on a snooker table -- that fundamentals, not aiming, is more important to focus on. Even way, way back in the early days of my involvement in these threads. The only time I ever got involved, was when the "cat's meow" thing came into play -- that this aiming system was a panacea for all things pool. Even now, with the toned-down atmosphere, there are blogs with claims that aiming is the "most important, a cornerstone" of good pool, with a gratuitous (and passing) wave-of-the-hand to fundamentals as a "yeah yeah, we all know a good stroke is important" checkbox-fulfillment thing.
Myself, I just got sick of these threads, and for a good long while, avoided them like the plague. When I'd login in the mornings and check the forum thread listing over a cup of coffee, and I'd see three new aiming system threads that popped up like mushrooms after a rain, I roll my eyes, go "not this again!", avoid them, and go about checking the other threads out. But lately I'd noticed these things got much more civil, and I open them to check them out.
Well Joey, the same thing can be said of you with your yaysayer/naysayer manifestos that Rodney Dangerfield (in the movie "Back to School") would hold in his hand, weigh it, and grade it as an "A" for sheer poundage.

However, I mirror the same compliment back to you in that they are always well-written (albeit no-doubt slanted in one direction), and you explain yourself quite well as well.
