Elevation is hard for GPSs to calculate as it requires a satellite near the horizon to be decently accurate. Honestly your 46ft elevation "change" is pretty "good" in my book.
Alternatively, some programs/computers use elevation maps during run processing (after you're done) to "calculate" the elevation. (Basically it plots your ride/run on an elevation map and just gets the elevation data from that.)
EDIT: Didn't realize the 510 had a barometer. Cool! My advice doesn't directly apply to it, but it does to devices that use GPS to find elevation.
