John, I’m curious. What creates more movement when down on the shot, the half tip pivot used in CTE or adjustments that have to be made from the fractional alignment
In my opinion the half tip pivot should not be defined as "movement" after one is down because one is not down on the shot until one is ready to shoot. To me movement is what happens when the player does anything to alter the vector from sending the cue ball straight down the line with a center ball hit.
All the physical action before that is part of the aiming process. And in that sense the cte manual pivot method produces exactly one move after the bridge hand hits the table, a pivot to center ball and the player is then in shooting position.
Any sort of fidgeting while down while down is less desirable in my opinion. If a method or teacher recommends such extra bridge hand movement while down then I would need to know why and take it to the table to test the method and figure out exactly what sort of physical moves are happening and whether I could get the same results without them.
The half tip pivot in manual CTE and the half ball pivot in 90/90 are clear moves that are part of the process and the efficacy of the results is highly satisfactory to me.
So personally for me, at least on paper at this point, any method that has me guessing at the aim after the initial perception choice is a backwards step in aiming.
I prefer the objectivity of choosing a perception, executing the correct visual sweep, landing my bridge with the tip pointed at a half tip offset, pivoting to center and being then in shooting position with no hesitation about the shot line I am on.
Following defined steps that allow me to use my eyes to align my body to objective references and end up on the shot line is very liberating. For me it really makes me bear down on the stroke delivery because I am not unsure of the aim and can divert my focus to the correct amount of speed and a straight delivery through the cueball.
While I agree that any objective reference use is better than none I have tried to aim in a similar fashion of starting with clear fractional overlaps and my body in a fractional hit position where I then choose by estimation/guessing how much thinner/thicker to adjust to and found it to be uncomfortable and far more mental effort with the result being that I was down on the shot with far less confidence that the shot line was correct.
I have also done the fidget after down method and personally find it to be quite uncomfortable and disconcerting.
So to answer your question, for me cte and 90/90 use clear, directed moves that greatly reduce the amount of mental effort and the amount of physical effort needed to go from standing analysis to shooting position in comparison to less formal "guessing" methods.
I personally think that this is why some users report that it feels like magic. I think the reduction in uncertainty frees the mind in very positive ways. Being more accurate with less effort when playing likely releases dopamine which causes feelings euphoria and reward.
On the contrary guessing in the form of a little of this a little of that leads to anxiety and trepidation in the execution in my opinion.
Watching the current us open one can see how being uncertain in the aim translates into mistakes in the execution for the nervous amateurs facing the seasoned pros. Pros on the other hand rarely waver in their stroke because, I believe, they are fully confident in their aim.
