Of course, where gathering this sort of data _is_ useful is diagnosing and fixing real latency so it obviously has merit. I just think it's ok to lean on taste and experience for most things UI/UX, including latency.
Another point, by couching the comparison in a less technical form (for example, rating a configuration/setup out of 5 stars or some similar approach), it protects from being "too methodological" during testing and data-gathering. One possible issue with the author's methods is if there are degenerative cases that are common in the day-to-day experience of a given configuration, they are unlikely to be present during the precise test that they have setup.

Not sure if I can follow but...no?! My first TFT-TV had 2 seconds input lag. Impossible to play video games on it. That has nothing to do with feelings.
Already 10ms delay has a measurable effect: https://www.youtube.com/watch?v=5qjSGEOEaXo
Can't say that I agree. I play rhythm games on a national level and benchmarking and reducing input latency is very important in those games.
The games I play (ITGmania) measure accuracy to the tenth of a millisecond, any fluctuation in your hardware latency can ruin your scores and nothing really is more annoying than an inconsistent setup where the latency change between or during a session is absolute hell.
Vibes and latency don't belong in the same sentence at all imo.
