Hi Maksym, ok let's look-up 15 degree at the table I referenced. The error is ~4%. Usually I get the same difference after I reduced the number of track points to a sane value. There are many factors that influence the value of the real distance. The zickzack of the GPS position adds distance. Ignoring the slope reduces the distance. The truth is somewhere in between.
