Sorry I've been out for a few days, catching up now. So to answer the main question posed:
It is true that Stan is physically rotating farther and farther as he moves through shots 1,2,3,4,5. Not because the pocket is a steeper cut, not because he knows he has to, not because he is making a conscious adjustment. He is just lining up CTEL/A the same as he does for each shot. However, there is some visual illusion at play here, because as you lock onto CTEL/A for each shot, the actual physical alignment is slightly different. This is the "visual intelligence" of CTE. This isn't something you have to adjust to, this is what our eyes tell us as we look at these spheres on a table.
You can do a test yourself: setup shot #1, line up CTEL/A, then look where CCB alignment falls on the OB. Then move to the next shot and line up again, and compare again. You will see that the alignment changes ever so slightly as you go across the table. Why this visual phenomena happens, I don't know.
This is why you CAN'T figure out this system just by reading a forum or watching a video. You HAVE to take it to the table and put in some time to get the AHA moment. And it WILL happen, regardless of what some people say about everyone seeing things differently. I think we are all capable of doing it.
My first thoughts of CTE were exactly the same: skeptical, dismissive. But I had nothing to lose and gave it a shot. Watched the DVD, scratched head, shrugged, started going through the motions and the shots. After a couple of weeks it started happening. It clicked, it worked, it was pretty exciting to figure out. Since then it has always been getting better.
