Did you determine the correct pivot point for each shaft???

woah !.....I never got a Joss cue from my father in law :angry::angry:
Really, it's nothing. After all, I am giving him my daughter.
With lasers.....
No.
I picked up the cues and shot each time attempting to shoot exactly the same. That's all. Nothing more. Hopefully, any difference observed was due to the cue.
But I think I failed.

Says the Jacksonville Project. Two of the important facts to come out of that experiment (besides the fact that LD technology does indeed work), were the size of the contact patch between the tip and CB, and the dwell time.
Dale...shoot a normal speed shot on any OB (any where on the ball) and observe the size of the chalk mark. It doesn't matter if you shoot off center or not, the chalk mark will be the same size. Even when you break, and there's a big chalk dot on the CB, the contact size is still 3mm...the rest is chalk dust blowback from the collision.

Joey...a "tip" of english is 1/8" or 3mm...so max is 3 tips or less than 1/2 inch. Anytime you're shooting off center you're striking the edge of the CB with the edge of the tip, whether the tip is flat or round.

I have never heard 1/8" is a TIP of English.
On center ball hit, the center of the tip hits the center of the ob .
If you hit the 6.5MM to the left or right of that ( which would be the edge of a 13MM tip ) , that to me would be a half a tip of English .
After all , you are hitting the CB half a tip from center .
Off center does not mean you are hitting the EDGE OF THE CB. In fact, hitting the edge of the cb wouldn't get the cb going forward.
If 1/8" off center is a TIP of english, how many tips would the lettering on this cue ball trainer ?

I don't think so.
3mm is the tip contact area. So why didn't you say that instead of misinformationing
a term that has been used for decades?
Consider:
The 'contact area' of the CB with the bed might be 1/32" or so.
If I tell you to draw the CB back 1 "ball width" would you really try to back it up 0.0325 inches?

I tell my medical students to measure their fingers in centimeters. Width and length. When they do a physical exam and need to note the size of something they can do it on the fly without a ruler if needed. I show them my hand (tiny, size 6 surgical glove). Telling me something is 3 fingers wide is crap unless you are using my fingers. I tell them if they don't get it down in 24 hours then I will have the measurements tattooed on their hands.
There are aberrations of observation that people argue about in pool. I have noticed this a lot. And people often entrench themselves in what they see even when empiric evidence indicates otherwise. That's more or less what my original post was getting at.
There are also aberrations of terminology. People argue about what terms mean.
There are also aberrations of measurements. We see this here in this conversation.
There is a lot more technology in pool these days. But the science usually seems to be catching up to the technology.
In science and medicine we formally recognize standards of terminology and measurement. Is there a formally recognized source to reference for such material in pool and billiards?
Just asking. :smile:
FYI: One young lady I taught contacted her father (a doctor) who contacted the family lawyer. The lawyer advised the young lady that I certainly could not have her tattooed which she conveyed to me. I told her she needed to stop calling daddy and deal with her own shit, and to advise her father to get a new lawyer because the current one wasn't too bright. Of course I could have her tattooed if I was willing to deal with the consequences. Dumb lawyer. It's all about decisions and consequences. She is a fine doctor today. Proud of her actually. She wasn't sure how to deal with me at first, but she learned. And she learned her hand measurements. :thumbup:

To test it, you need a pretty firm hit, otherwise swerve comes into play as caffeine notes.
It's not lag speed. It's probably a lot firmer than you think. Check out Dr. Dave's deflection test:
https://www.youtube.com/watch?v=nx4r0NSsxqo
That ball is probably going 3+ table lengths.
And yeah, we definitely have subconscious habits for aiming.
I know someone who swears they thought they were hitting the center CB,
and actually hit a little left every time. The brain is easily fooled.
Also worth noting is that the difference between the average cue, and a very low deflection
cue like a Z2 or something, is only about 30%. And the difference between the Z2 and the most
deflecty stiff break cue on earth will be only 50%.

My experiences are the same. I feel like a pariah in the pool hall, but I just don’t get what everybody tells me I am supposed to experience with my traditional ivory ferruled shafts. Trying to better understand, I purchased a Predator 314-2. It’s a fine shaft, no problem. But I don’t shoot better with it than I do with my older, traditional shafts. Since I prefer the feel of the older shafts, I haven’t changed.
