If I climb a mountain several times on different workouts, it always is within 3 feet on the summit.
My tracking / logging of exercise really helps keeping me motivated / going.

I'm pretty sure that elevation is through a barometer of some sort. You get elevation data indoors when there are no GPS signals present.
I do have smoothing on but the elevation data is ridiculous, 3000' of elevation change on a 5 mi route where the biggest hill is maybe 100' x4
The 500 is great and gives data that coincides w/ Google earth elevations and the totals are at the very least in the ball park and are also consistent over the same 30mi route
