"... against multiple [Stratum 1] sources..."
Baby, if you've ever wondered... whether it matters whether your sources
are strat 1 or not, now you know -- since there's no real way to get
provenance on down-strat time sources that I'm aware of.
Does the NTP code, people who know, give any extra credence to strat-1
sources in it's byzantine code?
