Wrong uphill and downhill in information screen after filling altitude data from SRTM

Here are two pictures (information and chart) for original recorded track:


And for the same track but with filled offline altitude SRTM data:


After filling altitude data, it is visible that there is to big difference in uphill and downhill data. In OruxMaps there isn`t that big difference in original and altered track:

I have the same problem, after correcting altitude with SRTM, I get much bigger uphill and downhill values.

It is calculating wrongly also on original recorded tracks, the values are just to high, in OruxMaps those values look better.

in latest locus version 2.13.1, computation of these values was quite a lot optimized, so now it should something between values received by orux/google earth/my tracks and few more apps that we tested.


there is no universal algorithm to compute these values, so it always will be little bit out of what you expect just now. Question is how far from real values is it
