I agree. The perspective scaling also depends on bridge length and the distance between the CB and the shooter's head, which will vary from one person to the next (and even from shot to shot). Also, if the person's vision center isn't aligned consistently and accurately both during and after the pre-pivot shift, the person's perception of everything might be misleading.Although I like the concept in the abstract, I don't know how well it can work at the table. It's a "perceptual trick" that I suspect different people will perceive very differently.I agree with PJ that using the apparent size of the OB to determine the pre-pivot cue shift could offer an improvement to the current versions of CTE.
Some CTE users probably also benefit from the help systems like CTE provide.Using the contact point directly is a quantum leap improvement over "indirect approximation" systems like CTE. Those who like systems like CTE probably have trouble "seeing" the contact point.Utilizing the contact point (or some other way to measure or characterize the amount of cut needed), as you have suggested in the past, could also help, but this would be "out of the spirit" of the CTE approach.
I think LAMas's pivot-adjustment system is different from CTE in another major way: it ignores the vague "visual" that's supposed to be "acquired" by using the "aimpoint" alignment (CB-edge-to-aimpointA/B/C). Instead LAMas simply shifts the cue parallel to the CTE line until it's pointing at the "reduced-by-perspective" aimpoint on the OB.
Do I have this right, LAMas?

Thanks.
Did I read your other post wrong? I jumped to the conclusion that you were trying to explain how perspective could fine tune CTE, but maybe you were describing your own system.
One thing I like about your approach is that the apparent size of the OB (and therefore the size of your prepivot cue shift) is directly proportional to the distance.

i would always go with the individual lesson over the class lessons, 100% of the instructors time will be focused just on you. (how many students are involved in this pool school during the same lesson?)
Really. Then why not give me a lesson as I requested? Uncle Nick is still coming to Toronto on Monday. I'm more than willing to pay for your time. Simply respond to my PM and we'll see you there.

And that is exactly what I question about the approach. It does not account for the fact that our perception of images at a distance plays many tricks on us.

Champ,
No brother....I'm coming to you. I have played PJ and I can tell you he knows how to use the business end of a cue. No world beater but plays well and is a great student of the game. I have hit a few balls in my lifetime and figure I can learn from Canada's resident CTH expert.
So will your mother let you come out and play Monday? For you its a can't lose proposition.
Nick
Beat you. I won't even play you. Show me CTH. Proof it works. I hand you $200. If you want to play that's your choice. Take my money and walk out. Should take you 20~30 min which would be the equivalent of $400/hr.
Nick
Let's stop boring the forum. PM me and we can work it out. Simple I put out the shot. You show me the line up and pivot etc. You watch me do it. I lock in and I shoot.
8 Balls in or more and you get the cash.
This might be a win win situation for you.Take the man up on his offer.Like i also have said in other pm's, i have a feeling all you want to do is beat me so you can come on here and brag,trash me,etc. like i have also said in many pm's, when i can see a normal,calm side to you i will meet and play you. I have a good idea of your speed and they have capped you around 9 or 10 there and lee brett is capped at 8-7 there and mora a 12. I know you can play.

Who really gives a sh!t how any of plays..really.Let sh!t go ,,try to have fun with things,
I really had to much time on my hands while unemployed for a time last year...LOL
Both balls rotate, so you can see where the CTE is.
Dead Crab where have you been?
I have added converging lines from the center of the CB to the edge of the smaller OB. I have also added a line from the left edge of the CB to the center of the OB. I have also added a line from the 1/4 point on the CB to the 3/4 point on the OB.
These lines converge through the OB to a vanishing point behind the OB - this is the conventional wisdom of perspective.
What I proffer is the parallel shift (heavy line) to the side of the CTE line that appears to be perfectly parallel to the original CTE line. One must divorce himself from the conventional perception of perspective and converging lines.
This can be done by disregarding the CB altogether while effecting the parallel shift.

I hope that this will help some here.:smile:
