Might be the fact that when your router is stratum 1, it will not have
another upstream ref clock other than itself. i.e. can't get better than
stratum 1 time source. A router with stratum 3 indicates that this is not
the "most accurate" time source as its upstream NTP source would be a
stratum 2 (if it had one) and then a stratum 1 serving that.
I'd have to test though to make sure...

Pete
