I am referring to about all pivot-style aiming methods where different bridge lengths are required for different shots, based on the distance between CC and OB. Instead of changing bridge/pivot point location, many players figure out a different way to make it work, like pivoting one tip right or left of CCB instead of from the CB edge. I've had enough friends over the last 20 years adopt one pivot system or another. From Shishabob to point-and-pivot or to manual CTE, they each say they made it their own by tweaking one aspect or another to make it work for them. If that has to happen then it's really a rote system, requiring a lot of trial and error before your brain finally figures out how to tune everything up. And the tune up may not involve the exact same tuning that another player requires. Even personal lessons often create varying methods in two different players.
It's like sitting through a lecture on on website design, then a week later an office buddy repeats something he heard the speaker say, but it's not how you remember it, not at all. So he goes and does it his way, while you do it your way, both of you thinking you are following the lesson as learned, but in reality you each develop your own way of achieving the same result.
This process doesn't apply to Poolology. There is one specific aim point for each shot. It probably doesn't apply to CTE Pro1 either, if the player is able to quickly understand and demonstrate how the visual sweeps lead to a CCB aim line. For those who can't understand or demonstrate the method, repeated misses will eventually lead to success. Like Thomas Edison supposedly said in an interview about finding a suitable material for his lightbulb filament.... "I have not failed 10,000 times. I have successfully found 10,000 ways that will not work."
It may take a week before it clicks for you, or it may take a year. Just keep trying it, and eventually it'll start working. This applies to anything skill-related, because skills are not taught....they are developed.
