Many years ago, I did a similar experiment, but to eliminate the
timebases from the measurement I used the PPS output as start
and the 10MHz input frequency as stop.

That way only the delay & jitter of the PPSDIV is measured (+ cables
& counters obviously).

The result were of similar magnitude.

Never attribute to malice what can adequately be explained by incompetence.
