Hey,
I don’t understand what’s going wrong with attached 1st slope (measured by vertical 2 and race 2).
Can someone explain me this?

When do you start activity on the watch? I usually start at ski center, then walk to the slope and it registers all the downhills automatically. I had some problems if I started skiing before getting GPS on the watch.
ps. Watch is Ocean, maybe it depends on hardware…
