Any ideas here...??
I have a Nokia N78 phone with GPS which includes their Sport Tracker software... it's a pretty good interface, and enables me to measure and log my running (yes I mean outside the car, with my LEGS)
BUT... I'm forever finding the figures for distances do not match with the ones my mate is getting on his Garmin running watch (which also uses GPS ). the difference can be about 10 percent.
My Nokia even logs different distances for the SAME five mile run - sometimes telling me the route is 4.9miles and sometimes up to 5.2m
I imagine lost GPS signal part way round could result in it jumping between locations and UNDER estimating distances.. but why would it often over-measure??

(ps - yes I know one solution would be to give up running and just drive round in the car.. but that's not really the point!)
