Regardless, the CB in my video is rolling with a large amount of sidespin (after any initial effects right off the secondary hit), so the comparison to John's shot is good.FYI, possible explanations and demonstrations can be found in this video:

Just to be sure you cover all your bases, when you hit a spinning cue ball with the object ball, the axis of the spinning cue ball changes due to torque and Bernoulli. So your "slow spinning ball" after hitting it with another ball , and it significantly changes direction would have a different leading edge force than a slow spinning ball that wasn't hit by another ball.
My cloth is not brand new, but it is also not significantly "broken in," so it will be a good (typical) example.My Simonis 760HR was stretched very tight by the pockets, and there is some weave distortion. I'll see if I can demonstrate a clear "weave bend" effect. If I can, I'll post a follow-up video.
Thanks for the suggestion,
Dave
PS: I still think natural "ball turn" was the dominant effect with John's unfortunate scratch, as demonstrated in my video.

I could be wrong, but the cloth didn't seem new to me. He had a set of attempts before in which he failed to get to 400. I'll ask.Are you sure, Bob? A couple quotes from John on Facebook:
Nov. 28: "I’m playing on a loose rebco 9 ft, new cloth and polished balls so great conditions."
Dec. 17: "I’d like to thank Ivan Lee of simonis cloth. He generously gave me cloth for the 14.1 I played this month to try to set new records.it was 760 and played great."
Did John have the table set up 5 or 6 months before he started his attempts? Or maybe he did another round of attempts prior to this most recent set?
Sounds like the more pertinent detail than the cloth is that of the Pro Cup Measle cue ball he was using for his 434 ball run? Was it new or older? If it wasn't checked out before the start of this run, surely after that nasty rolloff that ended the run, John or someone must have checked out that cue ball for a possible bulging dot?Are you sure, Bob?

... I agree, Dan. The CB wobbled as it came to a stop dozens of times all over the table.
Does anyone here know the proprietor of Easy Street Billiards? If so, would you mind speaking with him to see if the cue ball used by John for that run is still identifiable and if it could be examined closely for roundness, bulges, flat spots, etc. Is it a legitimate Aramith ball, or could it be a counterfeit? That last shot has certainly been of interest, and it would be nice to know whether a CB defect was a factor in the scratch. ...
Well, realkingcobra thinks cloth weave tracking could have been a factor. But I think a bunch of us would like to know more about the cue ball. I posted this last night:
The cloth for the run of 434 was brand new Simonis 760 at the start of John's attempts on Thursday, November 22nd. The 434 was on December 3rd, the 9th day of attempts and by that time John had finished 30 runs over 100 on the cloth. Thanks to Doug, John's racker, for the correction.
The cloth was new, but not brand new, for the scratch.

It is a pretty drive. One winter just after some rain, a boulder about the size of a Volkswagen Beetle had crossed the road about five minutes before I passed that spot. The boulder seemed to have bounced over the center divider which was undamaged. :shocked2: It is a very narrow two lanes in each direction but the drivers know how to compress to one lane when the emergency vehicles need to get by, which is often. But I digress....Thanks for following up on that, Bob. Now we need you to go back to that room, measure all the pocket specs, and examine the suspect cue ball closely (surely the proprietor hasn't lost track of it?).
[It's a pretty drive, right?]
Thanks for confirming. Although, in 14.1 there's not a whole lot of action down on that side of the table to break-in as much as the foot end. Could have still been fairly slick.
Thanks for the video. My only comment on this, besides giving John his due as the best current U.S. 14.1 player; is that the table has ridiculously large pockets with a very shallow shelf on those pockets. His very first shot of the run misses by a quarter diamond and bounces into the pocket! And also, Look at his shot in the first rack with 5 balls left on the table- he misses the 10 ball on a slow roll by a mile and it still dribbles into the pocket! Also the side pocket openings- that half moon shadow if you will) are VERY visible from the video view, demonstrating the lack of angle into those pockets and larger size of the opening as it protrudes well beyond the side pocket points, even on camera! I do appreciate John's 14.1 abilities, but, come on, what's next in this attempt at 527 in 2019- six inch pockets and smaller pool balls??? I just am not buying this- it has become a circus event; in my own opinion.
You could just admit you don't like John
FYI, I just spent some time at my table trying to find evidence that the weave direction could affect the motion of a ball, and I could not find any. I still think the primary cause of John's scratch was "ball turn" (and the fact that he lost control of the CB a bit).My Simonis 760HR was stretched very tight by the pockets, and there is some weave distortion. I'll see if I can demonstrate a clear "weave bend" effect. If I can, I'll post a follow-up video.Dave, why don't you do some research into grain tracking the balls!FYI, possible explanations and demonstrations can be found in this video:
