Elevation gain is always a difficult measurement. Even specialized watches like Garmin have a hard time doing a proper measurement.
With gps it is even more difficult. I see that the results measured with orux on my huawai are about 30% too much.
I wonder if this can be improved if DEM info can be used for elevation gain measurement!?
Accuracy could improved even more if the track on the map is used as a reference (aligned with the recorded track), so left right movement is eliminated...
Anyone else having accuracy issues?

Hello!
You can correct the track altitude, go to the track properties-->correct altitude.
You can test with different filters. Using good DEM files is the best option, combined with a smoothing with different radius can give you a very accuracy solution,
