How to Judge SPLIT HITS … Everything You Need to Know

You and Mark Rober could do a collab. I bet you could do it.
The most irritating to me was the guy on YouTube who said I said you should not use any physics knowledge, just go with the order of the contacts you can actually see. He said that after I objected to:Even worse, people will comment on the video post who OBVIOUSLY never watched it, and say the dumbest things! I had to refrain from blasting some of the people on facebook.

[BeginGarbage] BCA/WPA referee guidelines (which are different from the rulebook available to players) specify that the referee must see the foul itself in these situations. Watching for after-the-fact "evidence", such as the direction the cue ball travels after contact, is not the correct way to referee. You must actually SEE the wrong ball be hit first, to call it a foul shot .And as we all know, it's very difficult to see, especially when the shot is played with speed. Benefit of the doubt goes to the shooter. [EndGarbage]
Allot of other pro events these days.... are using video to go over situations to get the call right.
They are also using video to get the call wrong.
I think this is the “exception,” rather than the “rule.”
I would still rather they at least try to get questionable calls right with a review.
Bob,
Are you aware of any such unpublished guidelines? I mean obviously if they exist I’m presuming they don’t say that, but what DO they say?
The guy who claimed they exist did not respond to my request for more info. My guess is that if there are such guidelines, they were created by someone who doesn't follow the WSR (World Standardized Rules).
I dispute your assertion that use of an overhead close up slow motion video of the contact would ever result in a errored call.

It’s already happened several times, well documented.

Interesting that in your frozen ball/simultaneous hit scenario, whichever ball was hit first raced out of frame first, without exception. And the sibgle hit where you pretty much managed the nearly impossible actual simultaneous hit, the balls left the frame as a tie.
So it’s possible that distance traveled can be another indicator assuming the area after the hit affords room on the table to determine speed and distance.

There was one or a couple where the cue ball rocked left but if the ref missed that movement, no foul.
In league one night we had 2 situations where the shot was close, we would sometimes record them for review. The first hit was very very close, but a bad hit, the second was also very close but a good hit as we could essentially identify a specific frame. I ran both recorded videos through Google Gemini AI and it came to the exact same conclusion with detail. I asked it to analyze the Yapp shot and it came to the same conclusion as Dr Dave.
Perhaps through some test of 100s of close hits you could define the actual accuracy, but Gemini AI can also see every frame and come up with a conclusion. The benefit of using it in a professional setting is that you remove any human bias and its a true neutral third party making the decision.

That's true for a perfectly broadside shot as in the video or close to that, but usually the cue ball is coming in at an angle and that can make object ball speed more complicated.
Can you refer me to the video that would show it?
Why would that even be interesting? Mark has a very dedicated specialized fan base and is engaging.
