David,
I don't understand the question. The algorithm to calculate the select
dispersion has not changed since rfc1305. The rf1305 description has
been rewritten several times in many places, soI will not comment on
rfc1305. There are much more modern descriptions in the places I named.

But there can also be bugs in the written specification, and the
reference implementation has the advantage that it is proved to

The point of having a reference implementation for an RFC is that the
reference implementation is the definitive definition of the algorithm,
i.e. the reference implementation is correct, by
Dave,
I am sure that the algorithm is great, really. It is just that I can't figure
out from RFC 1305 how it gets calculated: "which can be calculated in a manner
similar to the filter dispersion described previously".
My first attempt was too similar and I ran the same data points th

he detailed calculations are in the refeence implementation document on
the NTP project page and in the NTPv4 Internet Draft. However, if the
select dispersion is excessive, it isn't because the algorithm is in
error; it's because you really do have large differences in the server

Which doesn't seem to include the deprecated version he is trying to

I think the advice here would be to forget about NTPV3 and use the

I am trying to validate an NTP implementation that is exhibiting a lot
of churn in the cluster algorithm. Unfortunately I don't think that I
been able to properly calculate the select dispersion based on RFC1305.
Can anyone refer me to a more detailed description of the calculations
