PART 2
The easiest way to determine the cue ball diamond is to forget about the numbers and just see the parallel lines, which cue ball diamond goes to which target diamond as in the attached diagram. Then you see where your cue ball is on the parallel grid and adjust accordingly. In the diagram the cue ball is ¼ the way past number 4 parallel line so you aim ¼ past the target diamond (2) along the same parallel line. The ball should end up at target diamond 7 or the corner pocket. Basically you shoot the ball in parallel with the existing parallel lines. Just remember which cue ball diamond connects to which target diamond and see the lines and shoot in parallel with the lines. I ran out of lines to draw but got most of them there.
If the desired end result is not the corner pocket, you adjust the target diamond by the amount your end target is away from the corner pocket. When both are off by a significant distance it changes the lines but most of the time you are shooting for close to the corner pocket so the target adjustment is minor.
This is an attempt to condense the subject of an entire book into about two pages. Hope it is understandable, the books are not. Happy trails.
