I see things pretty much as diagrammed except in 3D. The shooting part is down the stick centered but that's separate and too much text anyway. I use aerial marks (like DD's peace sign and other gestures) which allow me to do the visualization for many shots from behind the cue ball. For instance you can nail the tangent line using the edge of your hand right in front of your face. you can move it around to check all kinds of stuff no foul.
In short, I've done a lot to calibrate my PSR to the geometry. Generally I consider the stick itself a component of the shot and getting "chambered and locked in" is very high priority.

Ghost ball trick: It's the exact size as the object ball and always frozen to it. You can train your eyes by freezing the CB to another ball and walking around it till you memorize the look or you can no longer miss.

Also this might work:
A right triangle half the height of the object ball.View attachment 900128


Here's an interesting artifact of Jimmy Reid's Equal Angle Opposites:

The Yellow line shows the intended object ball line.
The Red line is contact line. You can use your stick on close shots to get the hang of it.
The Black line is the shot line running parallel to the Red contact line.
Notice, the Black shot line intersects the Yellow shot line at the base of the mythical Ghost Ball.
The blue line is just the line of centers.
The half ball hit is incidental. Could be any pool shot angle; different angles and parallelogram but the connection points would be the same.

The Richard Black story is funny. I'm guessing he knows exactly where all of the non perfect areas (I hesitate to call them flaws) are on the cues he builds but most normal people will probably never notice. Its the same with the racecar chassis' I build, I know every area that I don't consider "perfect" but the owners never or rarely notice, sometimes even when I point something out.
