You are not just paraphrasing you are grossly misrepresenting. Not intentionally but negligently because you are relaying what you heard instead of what I said. Now let me be clear what I mean. Sometimes when I am watching an instruction video (on anything) I will be half listening expecting to "easily" hear the important parts. Almost always I have to go back and pay attention.This is what I think 'objective' means:
ob·jec·tive
adjective
1.1.(of a person or their judgement) not influenced by personal feelings or opinions in considering and representing facts.
So please don't assume I mean something other than the definitions of the words I use. Forgive me if that seems overly frank. Just saying you shouldn't expect me to stretch the meanings of what I write.
So I'm clueless regarding the CTE method. However if it is 'objective' then it should be easy enough for me to set up a shot, follow the method to find the CB to OB aim line, and shoot. There should be no interpretation what so ever in this practice. I've watched some of John's vids, and he'll go through the motions saying that "this is this amount of a cut", "so I find CTE", "shift to 3" (or something), "walk into the shot and shift my body to the shot line"... etc. I'm paraphrasing so please don't take the quotes literally.
-So finding the center to edge alignment from CB to OB is objective
-Knowing the cut number based on the OB pocket line I would also imagine is objective
-The PSR mechanics are probably up to the user so not objective
-The shift into the shot line is the key to the whole thing it seems, so although it doesn't appear to be, lets call it objective.
So why can't the above be drawn out by one person and followed by another...? If you do your CTE calc and provide me with a path to shoot the CB down, then the OB should drop in the pocket. If that's not the case, then how can it be an 'objective' system...?
If you watch my videos I always start with the cte line, then I determine the perception (edge to a,b,c), then choose the sweep, then I go into ball address.
I don't ever say anything other than objective steps and I list them in order.
What i don't do is give all the detailed instructions for each step. I do videos that are more discussion and proof of concept than instruction.
Ok, past that.
Yes I can absolutely do the cte steps and establish a shot line for you to put your cue on.
Further more I could tell any proficient CTE user, they could tell ten more and any of them can do it as well.
And if you were a proficient cte user then I could tell you the "formula" and with that you would know exactly how to get to the shot line not influenced by personal feelings or opinions in considering and representing facts.
The "shift to shot line" as you put it is in fact very objective. If it were not then the line being pivoted to would not be correct some percentage of the time because the subjective nature of the task would cause inconsistency.
The much more important word is practicality.
What is getting on the correct shot line worth? Depending on how competitive you are it could be the difference between making profit or expense.
So it stands to reason that if any method produces the correct shot line consistently then that method is practical. Arguing about the amount of objectivity doesn't change the thing that the system does.
