Hello,
Did anything change in the way the optical heart rate is measured in the 5.00 update? I see some huge changes in my heart rate that I cannot explain due to weather, fitness, time of day, perceived fatigue, etc.
I do indoor spinning a couple of times a week and for over a year in general my heart rate zones are quite similar after every one hour workout, always at the same time of day, same music, same day:
However exactly after the 5.00 update the measured heart rate and zones changed considerably and has been looking like this for the last 4 workouts:
I have no indication as to why i am suddenly in zone 5 that much, it's jumped from the least used zone to the most used zone for every session since the 5.00 update. Coincidence?
Thanks Stefan
