I am quite disappointed with the Fenix 5 in some respects, one of which is the way that RHR is calculated (e.g. as an average of 4 hours during night) if I use my OHR. I do know that it is defined differently if I do not wear the watch during the night but for me one of the big selling points was the FirstBeat features that come with the watch. And hence, I also want to use the OHR.
Who is designing these features on the watch & the software? Everyone measures the resting heart rate as the daily minimum. Heck, I've measured this manually for a long time before buying Fenix 5 after waking up (and while sitting down) to monitor my fatigue levels.
What Garmin's definition of the RHR does is just hide all variation from the extreme values. Which is exactly what you are interested in if you are an athlete....If you see your daily minimum value go up it would usually mean that you have to take it easier. Now with the average my RHR does not really change, and hence does not allow me to react. For example, while I was recently sick my RHR defined by Garmin went up only by 1-2 points while my minimum values went up 6-8 points!
Before I could check the actual resting heart rate from Connect Mobile calendar function which showed the daily minimum. Now even this has been changed to the false RHR for some reason(!). I can still check the daily minimum from Connect web version but it's kind of a moot point to look at the daily heart rate data manually. There are a lot of cheaper multisport watches that can do the same stuff as the Fenix 5 if you take the FirstBeat stuff out.
Annoying!
