Hello,
I selected all the tracks in a folder and started statistics.
It seams that altitude is shown as sum of d+ and d-
I don't understand what this data means.
I think that only d+ and (but less important) d- are significant.(https://uploads.tapatalk-cdn.com/20170422/ac14941101f81369b646315a47c55735.jpg)
