I'm so confused about the active calories count showing on my Garmin Connect lately. I wear a fenix 5s. In particular, there was one day when I walked around NYC all day long, a total of ~12 miles. It shows that my active calories count is 76. On any other day while I'm mostly working at my desk, my active calories count can easily be 250 (not from active exercise like running or cycling) just from walking around the building/getting coffee, nowhere near as much walking as 26k+ steps. My partner wears an Apple watch and his watch said that he had burned 1000+ active calories over the course of the day. What gives??
Calories count for skiing is also (imo) wildly off. I was on the slopes for 4 hours the other day and it says I only burned 200 calories. That's way too low for even just 4 hours of consistent movement, let alone skiing.
