In the F5 manual, in the automatically detecting performance info, it says "The device can automatically detect your maximum heart rate......The device detects a maximum heart rate only when your heart rate is higher than the value set in your user profile"

In my user profile settings I have a a value of 172

Today I did a run getting a max hr of 179 but the user profile value did not changed, it stays at 172.

does someone knows how this work?

Thanks in advance
