@István-Török Based on many previous discussions, I got the impression that “Suunto resting HR” should be the HR when you are resting but still awake. Like when you are reading a book or watching telly.
Whenever I set my resting HR lower, my resources decreased like crazy…
For reference, my min HR at sleep is ~38, average min HR when sleeping is ~42. My resting HR is set to 53 and everything works reasonably well…
