I'm not sure if this is a bug or whatnot, but I get frustrated by the elevation graphs. On a recent run my lowpoint was 1252' above sea level and I topped out at 1483 feet. There were many little ups and downs along the way. When I look at the elevation graph, however, the Y-axis ranges from 1000' to 1750'. The resultant line just looks like a straight line with little bumps, all the detail is washed out and it turns out to be a useless graph.
It would rock if the Y-axis was closer to reality, so on this particular run, 1200'-1500' would have been appropriate.
