Hiking app calculates calories with a different algorithm than Waking. In accidental terrain we have slower speed (different pace) and higher HR so app adjusts burned calories accordingly. Besides, waking does not track ascend/decent values, where with hiking you get that info ad hoc.
I also think that adding hiking as an activity - especially living in the mountains - is a useful addition. The ascent/descent stats, the map, time and pace are all useful. Is the S62 incapable of recording such details ? I upgraded to a S62 from a Fenix 3HR, because I'm playing more golf now - but I don't want to have to keep swapping watches to get all other functionality that I had with the Fenix 3
