Recently, I began to notice the strange work of the altimeter.
I have made 2 bike rides with the absolutely the same route. In the middle of ride I paused the workout and swim in the lake for 10 minutes. After that I have continued the workout. After that I noticed that altimeter shows a biggest drop ever. I'm not sure that my workout might have been continued after such drop :)
And altimeter data for the same rides is not equal
