After almost one week after getting my first Garmin (Forerunner 955), I get a new insight: the ups and downs of stair climbing garmin. I average less floors climbed than floors descended. When I see my stats for the week everyday there are more floors descended than climbed. The thing is that I only do stairs at home and when I take the stairs up I definitely take them down again, so the amount should be equal as well. I climb stairs pretty fast, taking 2 steps at a time. It's quite frustrating that almost half the stairs climbed is not registered. It seems to me that this feature is quite broken. I already callibrated the altimeter (with the gps), so I don't really know what else I can do to make this feature work. (I'm not going to start climbing stairs step by step.) Any tips to make this feature work?
