CTE/Pro 1 is definitely different than any other "pivot" style aiming method, because the pivot or sweep is not in reference to any specific aim point or place on the object ball -- it is in reference to ccb, the "fixed" ccb you get when your body/vision is positioned at a certain cb perception based on the two line visuals between the cb and ob (CTE and ETA, B or C). This makes it better, imo, than other pivot systems. There is more to it in order to consistently get it to work, like specific bridge distances when manually pivoting, or experienced judgement when sweeping, but the two visuals definitely enhance the line of reference for the pivot/sweep.
And before any CTEers say I'm wrong about specific bridge distances needed for manually pivoting, just know I am only repeating the exact words Stan has said about the matter. And when I say "judgement" for sweeps it's because the sweep involves a precise bridge hand/V placement (just right or left of the fixed ccb perception/line). These are things learned through practice and trial and error. This is why it isn't something most players can do consistently right out of the box, and sometimes even after weeks or months of trying.
But everything takes practice in order to become consistent. The more times you successfully do something the more consistent you get at doing it. It doesn't matter if you pivot in reference to a specific spot on the ob based on the approximate angle of the shot, or if you pivot or sweep based on a specific "perception" of ccb, or if you aim straight at a spot on the ob with no pivot, or aim at an estimated ghostball, or estimated contact points, etc.... it all takes practice to develop consistency.
I happen to favor aiming methods that are more straightforward, meaning you stand directly behind the cb and fix your vision so that you imagine a line from ccb to the ob that will cause the ob to go the pocket. If you can visualize this line consistently you don't need any aiming system. But this is easier for some than others, because some people just have better spacial skills. That's where practice comes in. Some need more, some need less. Some aiming methods require more practice for some players but maybe not so much practice for others. Find a method that resonates with you and stick with it. However, if you've been using and practicing your method daily for several weeks or months, and you still find yourself missing a lot of shots, try a different aiming method because there are probably too many variables that rely on experience, and you won't develop consistency until each variable becomes consistent. Either that or your stroke is too inconsistent to allow you consistent results with your aiming method. Regardless, you're relying on the HAMB method, and it'll take a while.
