I don't doubt it's a good system for getting someone close enough for finer adjustments. But the exact same approach to a shot cannot cover two different shot angles. Stevie said that the first and second shot were the exact same approach and pivot, yet the second shot went off at twice the angle of the first.
If after Stevie's set up we could freeze Stevie, freeze the cue ball and freeze the object ball, but then move the table with its pockets from shot 1 to shot 2 you'd see that what you are claiming is impossible.
I don't have any doubts that the system works for many of you, only how it works for you. There are too many shotlines for the system to get you to all of them by itself. You are adjusting.
The Approach is the same. He follows the same steps, and the pivots are always done by the same amount. And the shot line is not a rough estimate, it is very precisely center pocket for a wide variety of shots, within each category
I understand how logically one could assume that the user must subconsciously make small adjustments somewhere along the line. That's really not true.
HOWEVER, when you follow the steps for lining up edge-to-A and center-to-edge (for example), you're lining up a fixed point to a fixed point and a fixed point to a fixed point, the same way every time, But you will get slightly different offsets depending on the shot.
Why that is, I don't know. But it's not some diabolical system that's just making you do a 30 degree half ball hit every time, and that's rough enough to make a lot of shots, and for anything close to 30, you kinda just fudge it up to make it work, or god forbid, pivot trying to increase or decrease the amount of pivot in order to make the ball (That would be insane).
You apply the steps to obtain the visuals for that specific category. Depending on whatever higher power, it'll give you an offset that is unique to that specific shot and slightly different to other shots that are like it. And then you pivot by the exact same amount you'd pivot for any of the other shots between straight-in and 60 degrees.
But no one is denying that there is variation. It's just not subconscious, and it happens in the process of lining up edge-to-A,B,C and center-to-edge. We can tell that we're aimed slightly thicker/thinner even though we're following the same steps.
Why the variation occurs when you're lining up the same two points on both the OB and CB is something I feel like I haven't heard an answer for that I would consider satisfactory for public use.
It honestly does occur, I don't know why it occurs, and I have only my word, which is absolutely not valid proof in any sense of the word.
I remember asking the exact same questions that you were and I never came up with a good enough answer. I just gave up trying to figure out why it works, and focusing on learning it.
