You're welcome. I aim to swerve. 🤓

FYI, I just added this image to the split hit resource page, providing a concise summary of almost everything in the video:

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.

Please post a video when you are done. 🤓

Thanks Bob. I was over complicating it. 0.1 mm doesn’t seem so tough for the shot in the video. I was able to get overlapping contact about 1 in 10 shots in the video. I wonder how much better a top player can do.

This could be calculated based on the compression of the balls, but I have not done this. I would guess the range is in between your two guesses, maybe in the 0.05mm to 0.01mm range, but that is a total guess. Faster speed would make the range a little bigger (since the balls would compress more).

Thank you!

I bet even a well designed machine would have a tough time achieving and repeating simultaneous hits. The balls still need to be set up absolutely perfectly every time, and the machine would need to be aligned (and stay aligned) perfectly relative to the balls, and the cloth in between the...

This is an interesting question, and it should probably be clarified in the rules. With thin hits, it is extremely rare the first ball is hit a second time, so there is reasonable certainly (no reasonable doubt) the 2nd ball is hit first when the first ball is back-cut. With miscues, it is...

That happens here quite a bit also, but I think it is much worse on Facebook. Thank you for being among the minority who actually watches my videos before commenting. 🤓

If overhead high-speed cameras are not available at “big pro events” (which should be the case), I think the ref should use their phone like everybody else does, even though it might not seem “professional.” Getting calls wrong is much more unprofessional.

Correct. In this rare situation, the benefit of the doubt goes to the shooter (unless video replay clearly shows a wrong-ball+first hit).

... only with slow-motion-video replay.

Good point. Understood. I guess I didn't want to emphasize it too much since it is such a rare occurrence. PS: I'm surprised you didn't complain about the length of this one like you have about other long videos in the past. But I am glad you seemed to make it all the way through. Good job! 🤓

Thanks. This one took a lot of work and time, but I think it was worth it (even though the video probably won't get lots of views since most players don't seem to care about this sort of thing).
