Hi John, as far as I know, Garmin does some kind of filtering/smoothing. The exact algorithm is unknown to me.
QLGT just adds precisely the intervals between subsequent trackpoints. For elevation the ascent/descent computed by this method is generally too high. To compensate this, Oliver has implemented a median filter in QLGT - give it a try. >From my experience it's quite usual that ascent/descent on a track measured by different devices varies by 10-20%.
