I have that. I think I based most of the rock on those diagrams, not the system. Those angles will always get you position.
This right here. bank systems and kick systems made me better at both but they still require a bit of feel and experience. After you work on them enough you will rarely need them while playing . You’ll just know. Plus your right..no table plays perfect And adjustments have to of course be made for speed and spin but they are a great starter point.
I will have you know I got all the way thru 5th grade. I don't know why you feel the need to try insulting me, I have been using the diamond system for many years and it is far from guessing Have a great day !
Parallel lines, numbers, actual visuals, are different ways of teaching, but there's a new buzz word being thrown around which supersedes all the rest. It can be found daily in AZB throughout the main forum and especially in the aiming forum. Yet it can't be pinpointed, described, categorized, defined, taught, shared, or seen.
Feel is about speed control more than aiming. Every see someone miss a ball and say they hit it too hard or too soft? That's feel. You have to combine it with the golden calf aiming system
If you want to get mathematical or scientific about it we could talk about collision induced throw, cling, swerve, deflection, gearing, etc. An aiming system is only one part of the equation, you still have to account for CB effects on the OB and such. Some systems admittedly have things built in to deal with CIT and such but it's being dealt with. How you purposely put your head "poke your head out" to reduce optical illusions is huge. You gotta see it right but you also have to hit it right. If you get good at chopping corners off of rectangles and visualizing CB paths it doesn't matter how you visualize them. It's fairly easy to map rebound angles and such on a rectangle. It's just 2 squares. Systems can give you a good starting point but I'm gonna say if you play your mentor and you both use the exact same system and he destroys you, he has better feel or better touch. Feel isn't everything but it gets you the final 10% towards a perfect hit. Sometimes feel is done by our subconscious. Muscle memory and our subconscious will win games if we just get out of the way and let it work. This is not to say you don't have to practice to get to that point. Even with the holy grail aiming system, if you don't put in the practice you will never improve. 
Feel isn't a part of it. It's only the VISUAL in what is SEEN. Very much more like below:
I think it also has to do with how tightly/lightly the cue is gripped as well as length of stroke or other manipulations. (Bhe)
Agreed. Most of the "hazards" you have listed above are many times overused or unnecessary by below pro level players.
BINGO! This is really HUGE! A "noser" directly over the cue for any and all shots will NOT understand what you just posted nor see it, nor think it's the better way to play and see shots. They're stuck in the one position unable to experience a "parallax view".
boogieman, you're growing on me, big time.If you get good at chopping corners off of rectangles and visualizing CB paths it doesn't matter how you visualize them.

I'm impressed...VERY impressed! (an unrelated sidenote... I'm quite partial to the info on pages 1 & 2)
