Exactly. I use the system on certain shots, basically as a solid backup to my natural feel. I originally came up with a version of it around 2002, using only the end rail for alignment values, considering the whole table as one "zone". It worked great on some shots, but not so great on others, so I used it sparingly.
Then a friend started using some aiming method where he would line up on the side of the CB, then pivot. It worked on some shots, but he found himself missing more often than before, which was never really that often. So he quit that pivot business. He plays great regardless - once put a 4-pack on me on my own tough 9ft table! Anyway, this was several years back, and I tried to explain my little fractional method for certain back cut shots. But he said it was too complicated to learn. So I worked on it and tweaked it until it wasn't so complicated.
I'm grateful for those of you that are finding value in it! I can't thank you enough for the support!
