Depends what you mean by "see". In the literal, empirical sense, no, I
haven't observed ntpd performance closely enough to possibly notice
this. But I think I understand from first principles why it happens,
and I'm researching Bayesian approaches to clock synchronization that
I think will improve both speed-of-convergence and asymptotic
precision.
