It means your graph is not what I thought it was, so ignore my original
comments.

Which offset column from loopstats? There are two offset in there.
Ah, I see below from column 2, the time offset.

So, essentially the same as my first graph here, but different scaling:
https://rellim.com/graphs/
I added the cstate boot parameter. Made a huge difference, but I'll
need a week to get a lot of data.
Loopstats Frequency Offset, went from 100 ppm to 0.4 ppm ± 0.2 ppm!
Now I can see when the LF goes up the timing suffers.
How does yours compare to the current graph?
