Feature Request: Analysing Tracks and calculated overall ascent

[rose28357]

I recorded a track during a trip in the alps (Kleinwalsertal). When i opened "Analyse" RouteConverter calculated a overall ascent of 2181 m. But we did not went that up and down ! Of course does our WintTex WBT-202 has fluctuations in measuring the high out of the GPS signal.

Is there a possibility to add something like a smooth function to get a better result for elevation profile?

Can you also add a analyze function for speed over distance?

i add my test case data in WBT-202 *.tes format.
