You're probably right, but my problem (if you can call having too many time sources a problem!) is that it's not intuitively clear which one of the servers is the best, other than that the WWVB server is significantly worse than the GPS and Cs ones. But the GPS and Cs ones have very similar performance. To the outside world it doesn't matter because the internet and even my firewall performance will mask differences at this level, but as an academic exercise, and on the local wire, I'd like to see if I can wring the best possible performance out of the system. I'm probably asking NTP to perform at a level it's not really designed for, and that perhaps the OS/hardware can't even support (in terms of system clock stability and time resolution -- though a longer term goal is to replace the mobo clock with a source derived from the Cs to solve at least one problem).
