As an aside, I couldn't get mpv to loop by pressing 'L', though it
reported A-B loop; instead I created an mpv.conf file with contents

loop-file=inf

I can confirm I see a pause at "23%", though mpv reports it as
00:00:00 and then a seeming jump or fast increment through
percentages. I would probably have to record the screen or something
to see exactly what happened, unless there's a way to get mpv to
produce a log.

Yes, that produces different but odd behaviour where the video
apparently 'freezes' while audio and file progress (%) continues.

You have done a rather interesting deep dive into the timestamps, Bs
and Ps, etc; I am happy to reproduce things for confirmation but I'm
just a monkey that uses ffmpeg for chopping things up and (less often)
putting them together- so while I've had an obvious interest this goes
beyond my expertise! Alas I have a few full plates I have to keep
spinning (to mix metaphors) otherwise I would be tempted to join you
in the bathysphere.

Cheers,
Rob
