Well I see know reason why anyone can't make his system work unless they have some kind of learning disability, etc ... people are set in their ways, don't like change, are comfortable with what they use, or have issues with stan, etc
The problem is that if you follow Stan's instructions "to the T" the system does not work. Maybe you don't realize what Stan actually says about his "objective" system. The operative thing you said is that you have to "make" his system work. In other words, if you use the initial alignment CTE provides you have to adjust the pivot or sweep depending on that particular shot. How much? That depends on the shot and knowing that requires a "feel" for the shot, just like any aiming system. Stan would have you believe that his system does that for you. I don't think even you believe that. If Stan would back off on that claim there would be no more flame wars and I think plenty of people would still use the system.
