Hemet Double Century data from Garmin 800, uploaded first to ST3, then exported from that program as a .tcx file which I uploaded to RWGPS.
I evidently had the Garmin "off" from the "lunch" stop until I was well back "on-route" on the second loop. Presumably this is adding mileage for the distance of the "straight as a crow flies" connecting line for the missing data, which would not be too much lower than the correct route without my 2nd loop extra credit (> 9.23 miles peddling, and that same distance back by car)
