As I suspected, you didn't understand what I was telling you in the pm. Maybe that's my fault as I didn't think a hiccup with the pivot was going to become a major thing. I said:
A hiccup? It was a complete and total failure. And something you should have been able to figure out in a couple of tries.
OK I tried again and I think I was being lazy with the pivots. Here's what I did and it works better, however, I still need a short approx 6" pivot distance to make it work. I line up the center of the cue to center cb and ob. Then I move the whole cue over to the right a half tip like a parallel shift. I think the taper on the cue was confusing my shift. Then after making sure I have repositioned my bridge hand I pivot to center cue. This works for the first three shots as long as my pivot distance is short.
The taper on the cue and tip size can affect the pivot and outcome. I thought I asked up front what your tip size was. No? Yes?
Is it much under 13mm?
The above was merely to describe how I diagnosed that my pivot was sloppy. I made sure that I was 1/2 tip offset with my bridge by parallel shifting and then pivoting to center. Whether it was the cue taper or my bridging over the rail that caused it I don't know. I'd have to set everything up again, which I will at some point, and take another look. Please also note that I said I got the shots to work with a short pivot length.
OK. Bridging should have been easily right on the rail, unless your rails are quite skinny.
You are leaving out context and are completely misreading what I'm saying. I am not saying that the balls go to the same place no matter how much I pivot. I'm saying that for a given CTE perception and a fixed pivot there is only one place the ob will go. If I set up edge to A and center to edge and pivot the same amount each time then there is only one place the object ball can go, period. CTE says that if I move the two balls over two inches then the angle will magically change and I will still pocket the ball. I'm saying that the result will be the same every time and the ball will track two inches away from the first shot because we moved the balls over two inches.
Based on what you did on those three balls all down along the side rail, you had 3 very different cut angles. The first ball was lined up to the left tip of the side pocket and the third ball was quite a distance away up the opposite side rail going toward the corner pocket. You used the exact same cue tip offset distance on all 3 shots and pivoted back to CCB on each.
As you just posted, ALL 3 shots went into the pocket. The balls didn't track differently. They all 3 went into the side pocket.
I guess it's time for you to try twisting it into something else and say otherwise.
