Why? Can you adjust data recording to 1-sec intervals? It'll reduce battery-life, but improve accuracy. It's a bit bulky though - use the Strava app on phone instead?
I'll give that a go - haven't owned the garmin for that long so still trying to get used to it. My phone flaps about in my pocket but the garmin hides away fine in a rear jersey pocket.
