Mine is hanging out around 59 (which I think is really high for what it should be). What that high with band 1, then with band 2, no change yet since update.
My main exercise is a bike commute, very little running, although I use the run tile for hikes. My theory is that my mainly downhill morning commute has a high heart rate, but not because of excursion, because I'm very alert and around traffic, and cold, in winter typical near or below freezing, as a result falsely quick recovery. I thought maybe the altimeter on the band 2 would change this, but just dropped from 59.3 to 59.0.
Also live at 5000ft, but not sure if that has impact, but sounds like if anything that would lower it?
I thought health vault had VO2 history, but couldn't find it. I think when I first got band 1 was around 49?
