Here's another one....

I'm not sure about bridge distances, other than a longer bridge distance would create smaller angles and shorter bridge distance would create bigger angles. And this only pertains to strict manual pivots, certainly not Pro1 sweeps.
As far as angle difference between inside and outside pivots... Using a straight in shot and working backwards, knowing that an exact 1/2 tip pivot must be used, and knowing the exact bridge length I used was 9" (which gives a pivot angle of 1.4° through ccb), it's pretty simple to reverse engineer the math and come up with the shot angles. The outside pivot leads to a center to center alignment, so that's a given starting point, the "outside" pivot line. Rotating this line through center cb at a pivot angle of 1.4° will lead to the perception line. It's from this line that each offset pivot originates. So rotating another 1.4° through ccb takes us to the "inside" pivot line. In the example I provided (ob 25" from cb), the resulting shot angles produced for thick and thin, are 0° and 32.9°. The perception itself would produce a 15.8° shot if used, but it's never used.
I don't know the answer to your last question. That is where I quit trying to make it work, because the balls do not "present themselves differently" for me anytime the same setup is located elsewhere on the table. Maybe the book or truth will explain that little tidbit.
