I found very consistent results after a month of collecting the data.
It gains about 1 second a day dial up, and loses 1 second a day crown up.
Now I use those 2 resting methods each night when I take it off depending on it's current accuracy.
It keeps the watch within +1/-1 second from accurate consistently.
Last time I set the watch was 3-4 weeks ago after it ran out of power and it's +.5 seconds fast as of right now and that's generally where it sits.
My advice would be to skip the machines and just take real world data samples. Find out how your individual watch reacts to resting position. See if you can correct inaccuracy with resting position. If you can't, it probably needs a service.

A great old school approach
The KISS principal in practice where one simply enjoys their watch and manages it in a proficient manner based on common sense.
Sometimes it doesn't pay to pick things apart too much and over analyse
Of course, some people may enjoy disecting every aspect of something until they kill it, and so be it.
