FWIW I posted some stats from my Raspberry Pi with a GPS module here[1] along with a VM on the same LAN. The tl/dr of the Pi:

    $ chronyc sourcestats
    210 Number of sources = 7
    Name/IP Address            NP  NR  Span  Frequency  Freq Skew  Offset  Std Dev
    ==============================================================================
    PPS1                        8   6   112     -0.018      0.020   -105ns   336ns
The other computers on the LAN have typically ~30uS std dev.
