Probably not necessary, but maybe helpful - Here is a screen recording of it along with a log. Going from 13% to full charge. It happens for me at 74% in this test and the clock begins to recover at 83%. My thought is it has to do with when the charger switches from constant current to constant voltage. It’s very interesting that the clock changes practically at the same time that the percentage display ticks over from 73% to 74% and from 82% to 83%. Could be a coincidence.
