Does your Garmin have a heart rate sensor? Trace I am pretty sure applies a generic ski calorie burning formula. I don't remember putting any demographic info into Trace. If Trace reports basal + active, that is kind of annoying... It might make sense though. Otherwise it would read something like 1 hour of skiing, 13 minutes of on snow time, 35 calories burned hahaha.
I found a lot of variability (> 10-15%) between ski app vertical reported. I run Trace on my phone and AllSnow at the same time and at the end of a 30k vertical day will have a 5k difference between the app. Testing at places with a single lift, like Wildcat or Crotched, I find that Trace actually under reports vertical by that same 10-15% margin, unless the lift vertical reported by Wildcat and Crotched (and on newenglandskihistory.com) are wrong.
Yes, the watch has an optical wrist HR sensor (It is the Garmin Fenix 3 HR)... Also, there is an available chest strap you can buy that is more accurate than the wrist based one, but I have just been using the wrist one.
Another neat data trend is seeing my heart rate while skiing (both average and peak) decrease over the season, thanks to dropping a bunch of weight and being in better ski shape as the season has progressed.
My first day skiing this year (Dec. 9 @ Loon) I had an Avg. Heart Rate of 163bpm and a Max of 191bpm.
On Tuesday, the average was 122bpm and the max was 156bpm.
I used the data to graph my heart rate over the season, and there is a very clear trend line connecting the first data point and the last.
