What worries me more is that 999 ms
offset at one point, which suggests that the nmea sentence came too late
and the pulse got associated with the wrong second. (The garmin 18x had
this trouble a lot apparently).
Yes, Bill, I noticed that as well, and that some of the offsets might have
been just about the pulse width, hence my question about using the wrong
edge.
Some Garmin GPS 18x LVC firmware versions had the late NMEA problem. For
anyone who has not yet updated their firmware to 3.70, you can get the
update from Garmin.

Instructions:

The earlier GPS 18 LVC was not affected
