"Pivot to Center Ball"

Dave, still trying to figure out what "arc along the OB plane" actually means? Isn't an "arc" simply a portion of a circle when viewed from the top? Isn't the "OB plane" a line when viewed from the top? Is the illustration below close to what you're saying? If so, which arc (A, B, C, D, none of the above) do you pick? Or am I totally off?

Looks to be between A/B. B is def the closest. This is a great picture of what I'm saying.

It's all the same. The 1/2 tip pivot was chosen for the DVD because it's the easiest to execute and hardest to mess up. It's the most objective in order to do what matters--- make the OB. The smaller the pivot, the more the shot circle stuff is irrelevant.

How do you do that systematically? Easy-- just let the skin move a fraction. The base of your bridge never moves.

Do you actually understand the meaning of the words exact or systematic? I'm starting to think this whole debate is due to a language barrier between you and everyone else.
 
Before you ask---I need to clarify my answer above. I based that on the CB/OB distance in the diagram.

Go ahead and ask.
So what you're saying with this "shot circle" stuff is that the pivot point changes with the CB/OB distance? Different pivot lengths for different CB/OB distances doesn't add to the small handful of cut angles defined by the system. It just means there's a different handful for each distance.

It's broader than that - it's a cognitive barrier. And it's not just Spidey - it's all the CTE "defenders". They truly don't understand this entire topic - and they don't understand that either!

I think that's probably an important CTE system requirement: the less you understand it the better it works.

So in other words, you have to figure out the exact amount of curvature of the arc based on the CB/OB distance? And that is supposed to be more precise than determining the pivot point based on CB/OB distance? (And I'm sure you're aware of this but for the geometry-challenged, the amount of arc curvature is directly dependent on the pivot point distance. The "flatter" the curve, the further the back the pivot point is.)

So when you say...

You pretend your cue extends to the OB plane and when you pivot, you "arc" along this plane.

...that is still a completely indefinite/ambiguous instruction, considering there are an infinite number of arcs tangent to the OB plane with different degrees of curvature. You have to determine how much curve the arc should have based on the CB/OB distance. Does your system or any other pivot system systematically tell exactly which arc to pick?

Not only that, but you have to believe that the system will line you up perfectly on every shot. It's the placebo effect.

But, that not to say that it's necessarily "bad". If something works, then continue to do it. Placebo or not, why stop if you get the results you're looking for?

Or to put it more simply: "arcing along the plane" = pivoting at the center of the circle that contains the arc (apparently where the CB is midway between the pivot point and the OB). The fact that Spidey needs to have this simple and obvious fact pointed out pretty much undermines his credibility as CTE's "technical consultant" - and CTE's credibility as a system that understands itself.

I'm not bashing here but all this work hardly seems worth the effort. It's amazing the same people who can see the center of the ball, the edge of the ball, a shot plane, curvature of the arc?, shot circles?, and all that jazz cannot see the part of the OB that needs to be hit to pocket the ball.

CTE users don't do all that stuff. They use CTE as a pre-shot routine that helps them align themselves consistently and gives them the confidence they need to aim by feel. That makes it a pretty helpful system, but ordinary CTE users don't understand it and have become convinced by other CTE "defenders" that it's a lie perpetrated by people who "hate" CTE. Go figure.

Spidey comes up with this "shot arc" stuff to try to prove (mostly to himself) that CTE works "exactly" without "feel". We're just repeating the facts here for other readers until the truth finally dawns on him (personally, I don't think he can gracefully get out of the corner he's backed himself into).

What corner?? Just because you don't understand perspective and how that applies to this discussion doesn't mean I'm "cornered." There's plenty to be figured out and unlike you, I don't pretend to know everything as far as what's going on.

Hal has explained many times (as it's been discussed over the years) that we're discussing a 3D proof, not a 2D as you repeatedly claim. Your consistent banter on how everyone's wrong but you and how this stuff is 2D because of X, Y and Z is old.

The more precise I am in my movements, the closer to center pocket the ball goes--- not my "last minute feel adjustments."

Since you know everything when it comes to pocketing balls--- how about you post a video of yourself running Colin's shot test. Lou can do the same. In fact, you...Dr. Dave and Lou can each run through the test 1 time and I think I'm even money to score same or better than your entire group in 1 try. I've only been playing 1 hole for like 30 days... give me another 30 and I think I'm even money with you at that game as well (and you've prob been playing that your whole life).

Backed into corners, please.

Why not explain it to us and finish me off?

Hal has less of a clue than you do. He thinks these systems work because a pool table's dimensions are 2:1 and 15+30+45=90. (Oops, did I just blaspheme?)

You should try some of that "because of X, Y and Z" stuff.

When will you realize that these meaningless challenges only prove that you don't have a clue what we're talking about?

Hal posted that 2:1 crap as a joke, to make fun of the math guys on the forums...namely, you.

Hal has more pool smarts in the back pocket of his other pants than you and your cohorts have duct-taped together.

I don't think any of those comments are meaningless, nor are they "challenges." They're simply points that most of the people you knock on here likely pocket balls way better than you.
 
Spidey:

Yeah, I'm still laughing more than a decade later.

I don't think trying to knock anybody's pool playing skills (especially those I've never seen play) is necessary to make my points. You seem to feel otherwise. One more difference between us.
