Resting HR algoritm

Hi
Can someone explain the resting HR calculation on the watch? I thought it the lowest HR during the day. But its not. Than I red somewhere, when wearing the watch on hand over night, it is somehow calculated as average for the night? But is really the watch evaluating whether I am at sleep or not, or is it Connect after the sync? Than how can I see the resting HR on my watch before the sync with the phone in the morning?

All these questions are just because recently my RHR increased significantly, from 45 to 65/70, having crazy peaks. On days when I am really rested and I see high values, and recently after 100 km bike ride the next morning I see 51... so not sure I can trust it...
  • Just a thought but if you look at your stress widget do you have a lot of empty spaces with no readings? if so maybe its because its not getting proper HR readings during the night and you need to make sure the watch is not too loose on your wrist for example.

    I tried various tightness of the watch, and I also get constant readings on the stress widget. I also checked the values of HR in the Health app on my iPhone, there are constant readings throughout the night, just the RHR calculation is strange...

    RHR: This value is for the current day. It is calculated one of two ways. For users that wear their device while sleeping, the device will read and record the average of all readings while they sleep, excluding periods where any steps were detected or the measured heart rate fall outside reasonable bounds. A minimum of four hours of sleep time is required to register a reading. For users that do not wear their device overnight, RHR is determined as the lowest average reading over a one minute time period during the day.

    7-day Average RHR: Some devices will display a 7-day average value which is the daily average resting heart rate over the last seven days. It is a rolling value and does not reset at the beginning of each week.
