Agree that we should try to explain it in other ways, but I also find using the language that Stan uses helpful in being consistent.
For me, there were a few difficult things that you have to get past in order to "get" the system, assuming you are trying to analyze it before just trying it out as described at a table:
1) Where to aim. You aren't really aiming at any specific thing - point on the ball, on the table, etc. You pick up the lines (visuals) as described, and when you have that good, solid picture of the OB, you simply slide in toward the OB along that line, tunnel, plane, etc., however you want to look at it. For the manual version, that means you are sliding in down the line of aim with your tip offset 1/2 tip on the proper side for the shot.
I know it seems weird, and I've seen the question asked a bunch of times, and I for one can't explain it, but it works. I use the CTE line as more of starting reference, then I shift eyes/head as necessary to pick up the secondary aim line. Once I "see" that picture, I know I'm visually lined up correctly. With just a bit of practice, your bridge hand will align with your visual picture of the shot, just like it does when you are using any other method - we don't usually look at the table when placing our bridge hand using ghost ball or anything else, our brain is very good at putting it in the right position to hit the spot our eyes are looking at
2) Knowing when to use what aim line and pivot. This is not summarized in the DVD but rather taught through a bunch of examples that you have to work through, and working through those is key to understanding the system and seeing that it works. It has been summarized here in many different threads, and I'm sure myself and others would be happy to do so again for anyone struggling with this after watching the DVD.
3) Getting used to the pivoting concept, and learning to trust the shot. For me, the pivoting wasn't nearly as bad as I thought it would be, especially once I switched to Pro1, it's so seamless now I doubt anyone can even tell that I'm doing it. Even when done manually someone would really have to watch you once it's ingrained into your routine.
If you follow the instructions on the DVD, ask any questions you have here on the forum, and suspend your preconceived notions of aiming the way you always have, I think you'll find that the system works as described, and if you find you pocket balls better with it than it might be something to adopt.
