more than just splitting the UDP/IP path to the lower stratum servers in

still takes your NTP server with it. So what is it? Do you perhaps
The big advantage of such a setup is that all your systems will agree
on the same time. Locally you have short roundtrip time variations so
the polls of the local NTP server have small jitter and are not affected
by the loading of the internet link.
It is usually more important that all systems have the same time, than
that this time is very accurate.
If you can get all systems to agree on the time it's usually no more
difficult to get them to agree on the *correct* time! The rock solid
"beat" of a GPS is easy for most clocks to march to!
