I agree with this wholeheartedly; that is the real question of interest.
The annoying part is that the tools needed to determine what really happens have been around for over 40 years. Almost any decent Biomechanics department will have somebody with the tools needed to record, analyze, and display the body motions. No trying to interpret what people say, no staring at fuzzy YouTube videos, none of that; just nice clear results. Even eye tracking shouldn't be a problem, though it'd probably mean tracking down a CogSci type with the right equipment. Eye tracking at distances we care about seems to use much larger time intervals between samples than we would want, but I'm not real knowledgeable about that stuff, certainly not current, and I suspect that's more a function of what they're studying than any limitations in modern equipment.
Unfortunately, I can't think of any reason some funding agency might care about this or something similar enough that we'd get the data we want.
I have been diagramming CTE and now Pro 1 with more difinitive results. I believe that it is a tribute to the human mind. Those that master it and it's derivatives have to commit to memory so many aspects of CTE.
The have to memorize cut angles.
Relate those angles to solutions that include:
- Parallel shift of the cue to say 1/2 tip or more or less shift for the distance between the CB and OB.
- Or, adjust the bridge distance behind the CB.
- Now with Pro 1, be able to equate those solutions to the secondary aim points.
- Be able to assume a stance without the shift or pivot in line with the GB.
I cannot fathom that high level of recalling from ones memory of these elements.
I am fortunate to be able visualize the GB and effect DD aiming and run racks of 9 ball. These aiming methods are predicated on being able to see the contact point on the OB that sends the OB to the pocket/target.
Why one would choose to do otherwise escapes me for they are more parsimonious, but some must use CTE to accomplish the same results or better.
I believe that the mind and a great memory makes CTE work and is geometrically diagrammable - I have done it.
CTE and it's derivatives are tools to advance one's game for those that can't or won't embrace GB and DD aiming.
If it works for you - kudos.:thumbup:
