I guess my point is that it doesn't matter how many aim lines are needed to pocket a ball from anywhere on the table. All that matters is the handful that pertains to cut angle you're looking at. I mean, it's not like you look at a shot and think, "Damn, I have over 100 choices here!
Which one is it??" Lol.
Instead, if your estimates are even remotely decent, you really only have to choose one from about 3 to 8 choices at most, depending on ob distance from the pocket.
For players with little experience, the odds are pretty good that they'll guess/estimate a good aim line quite often when the ball is closer to the pocket, because there might only be 3 or less aim line options. From farther out, traditionally, it takes a lot of trial and error before the player is able to narrow the shot down to just 1 or 2 aiming options out of about 8 to choose from.
And once the player begins to sink more shots than he misses, he'll finally start the process of successfully repeating those shots enough times to secure them to memory. All the time spent to arrive at this level was due to a lot of trial and error training the mind to narrow down or fine tune all the aiming options for a given cut shot.
But here's what Sharivari and other great instructors or pool experts don't get, or simply don't acknowledge: A player can use traditional methods of estimating the correct aim line (using ghostball or traditional fractional references or contact points, etc....), and eventually, after enough misses and makes, they'll be able to recognize the correct aim or alignment more often. Or they could use a good system that dramatically reduces or eliminates much of the trial and error or guesswork or estimations that are inherent with those traditional aiming methods. This allows the player to get an aim line for most shots without having to go through that time-consuming trial and error phase. A good system simply narrows the shot options down, reducing or eliminating the amount of guesswork or estimations needed.
Whether using traditional trial and error aiming methods to program the mind, or a good system/method to program the mind, the end result is the same.... The player develops a good eye for simply recognizing shots and knowing where to align or aim. The only difference is the amount of time one has to invest in order to reach that point of development.
