You provided a thought experiment about which is quoted. I reject it, because it is not based on what I said or what I claim. Instead, here is a better thought experiment...
Take an APA SL5, give that person SVB's stroke. Would they or would they not almost instantly go up several levels? I say that because an SL5 has decent aiming. Can aim most shots. Now, for the sake of this thought experiment, I am excluding game-knowledge (position play, routes, strategy). They may miss some shots because of wrong aim. Sure.
Now, take that same APA SL5 ...but instead of having SVB's stroke, they now have Stan Shuffett's ability to determine perfect aim lines. Will they be as good? They'll improve because that mediocre/decent aim will now become near flawless aim. But, that potential will never be realized because their stroke sucks. And yes, APA SL5's have poor stroke. This assumes that CTE even works in the first place. But this is for the sake of argument.
Either way they will improve several levels.
What is the difference in my thought experiment? I assume an intermediate level of aiming knowledge and skill. I don't think there's anyone, short of a complete first day beginner, who doesn't have some aiming ability. Your experiment is extreme for that reason, and not based on what I am claiming.
And yet you don't assume the same level of skill for all the APA 7s and 9s that post here who use Stan's and Hal's methods? Any time a player says that they are a high B to A player or even players of A+ quality like James Roberts you and others just gloss over that evidence. My experiment cuts directly to the heart of the matter. You can have a world class stroke and still not find the right line all the time. That not finding a right line leads to inexplicable misses AND body english. So in order to eliminate ONE variable it's important to figure out how to aim in such a way as to put the aiming beyond question. THEN you can move on to the stroke and make sure that it's working right.
For the 20th time, what is holding people back the most is stroke.
And for the 20th time this is your opinion and not based in any kind of factual knowledge. See above where people who already had world class strokes and fundamentals changed ONE THING about their game, that one thing being how they line up, and reported major improvement. And when a world class player reports major improvement then perhaps you might want to allow their testimony to count.
We've all seen those drills that are designed to improve stroke/cuing accuracy, as well as expose flaws. If a player tries those, and is not consistently getting perfect execution or results - why would they successfully execute one of those cut shots in CTE? The margin of error in their cuing and stroke is enough to miss many of these cuts. Am I or am I not right saying that? Most people cannot hit the CB exactly where needed on a consistent basis. Because of that, the CB goes in a direction they don't intent. And thus, shots are missed and positions are botched. More often than not, the intermediate player has a plenty fine line of aim and understanding of where to send the ball.
The thing is that you are determined to make it one or the other despite saying that you aren't. You generalize a lot. On one hand you claim that MOST players can aim just fine (although you have no evidence of this) and on the other hand you claim MOST players can't hit the ball where they intend to and you also have no evidence of this. You want aiming system users to give you precise directions and the precise math why their methods work but you counter with generalizations backed by nothing but speculation.
My contention is that if aiming were NOT an issue and were SO easy as you claim then it would be not at all talked about on here. You are so quick to dismiss the experience of experienced players and marginalize their descriptions of how their games improved by virtue of learning an aiming system but at the same time you offer nothing but opinionated generalizations.
I understand your position but the evidence is not on your side. At least not on this forum.
On this forum you have MANY users who reported great improvement by learning an aiming system. SOME of those users had stroking issues to deal with as well and they reported that they found that they had to ALSO improve their stroke to use the aiming system properly. This can go back to your tool box analogy. As in when you get one tool but you can't use it until you have mastered another one. Both are important and both are the yin/yang of shot making. I can agree that improvement in one brings improvement in the other but I certainly do not agree that players are forsaking working on the stroke for the "diet pill" (as you put it) of aiming.
My advice, those stroke precision tests and drills....if a player isn't scoring very well on those with good consistency....don't worry too much about "aiming systems" yet. Definitely aim, definitely keep learning all aspects of the game. Including aim. But you've got bigger fish to fry!
And my thought is that the fish is the same size. Intertwined. Proper aiming exposes stroke flaws in those who have stroke flaws, proper stroking reveals aiming flaws. No matter how you look at it there is no complete player without mastery of both.
