Yes, it's the difference between send (20 Mbps) and receive (200
Mbps) and that
asymmetry which introduces an unknown path delay difference which
accounted for, and hence the offset I noted. As there will be a
all that NTP does is to use the average.
For low interrupt latency from the serial port control lines - the
the PPS signal - even the Raspberry Pi 1 is significantly better
than a typical Windows PC, at least using standard device drivers.
