I actually benchmarked the on in the PRS10 by feeding it a 1PPS
generated from another Rb that was deliberately adjust approx 1e-10

I can't seem to find the results anymore, but if any of you want to
reproduce it, it was a pretty trivial setup.

As I remember it, the standard deviation was approx 3nsec, and I
seeing some "missing codes", Ie: readings that just didn't
happen in practice.

Testing any other such design is similarly trivial.

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