from my peer_summary file:
id mean rms max
127.127.20.2 -65.605 16.583 83.926
127.127.22.2 0.000 0.005 0.039
so getting any sense out of the nmea data for my 'Sure'
GPS only gives an approximate time. For my Garmin which
I didn't update, the performance was better than above
but at least one of the updates would have rendered it
useless for timestamps.
