Wrong. Aiming systems are peddled like diet systems. Aiming systems get a lot of talk in a controversial sense because people are calling out what BS many of them are. People like things to be proved to them.
Aiming system people make the claims; therefore, the burden of proof is on them to prove it works.
Don't want so much talk about it? Don't make unsubstantiated claims. Instead, what we get is vague descriptions of the system. Lots of qualifying statements (excuses), footnotes and asterisks, warning labels, emphatic testimonials based on nothing concrete....
Aiming systems is a kin to the late night infomercial.
Good topic, good discussion. Thanks for posting it. I'm guessing that most of the controversy of "aiming systems" revolves around one known as CTE, or counterparts thereof. First of all, no aiming system is going to make up for poor fundamentals. There is no way around that. So given the same basic playing ability for a given player, the only difference between aiming systems is how they approach shot alignment. Some use invisible points, some use invisible balls, some use edges and fractions of balls, etc. That is pretty much it. Any one of these methods of aiming will have its levels of success for any given person, and the amount of effort will vary. No one is forcing an aiming system on anyone, they are there for you to try or not try as you wish. As for vague descriptions, that was true and there was no clear description of the system in its entirety, until a few days ago. There is a post here (from me) that spells out the original CTE system. It's free to read, free to try, no strings attached. It should be pretty clear how it works. So why do you miss shots? It's not the aiming system, it's human error. For me (yes here is your unsubstantiated claim) the objectiveness of centers and edges minimizes the human error part of the equation, especially for the tougher shots. That may not be true for others, I don't have the statistics.
