Resting heart rate calculation

[Tbrads]

Has anyone noticed that resting heart rate calculations seem to put more weight on historical data points than previously? I've observed this happening to the extent that it seems to make RHR inaccurate...

For example, I currently have Covid and that's put my HR up a lot, as expected. I'm on day 3 and recovering and last night my sleeping heart rate was 65 (the previous night was 73!). Since getting up, my actual heart rate when sitting down has rarely been over 70 - but my RHR has been calculated as 73, higher than yesterday's 72. So when my HR was actually high yesterday, Fitbit says it was lower than today when the reverse is true.

I've observed similar trends after drinking alcohol.

I didn't seem to have this issue with my charge 4, just my versa 3 - not sure if it's a device thing or a change to the algorithm.

Hi @Tbrads - you will see RHR in your Health Metrics calculated each morning [so presumably using mainly the rest period over night] and may not change during the day, regardless of your HR.Try comparing the overnight HR graphs.

The watch may detect all sorts of weird and wonderful things, try taking your blood pressure also. It may even tell you when you are getting better before you feel better or the inverse, so following the trends is useful.
