Improvements to the resting heart rate algorithm

Noting the above line in the change log.

Do we know what has actually been changed? I'm fairly sure I remember reading that the resting HR was the lowest average for a minute. Does this mean thats changed? I often see my own HR a good 5-7 beats lower that what Garmin takes as the rHR - and I assume that's because it doesn't stay that low for a full minute at a time. It would make far more sense to me for Garmin to just read the lowest it sees!

Really? So if there's one measurement error, you would want to see that as low resting HR? Well you would get low numbers, but I rather have better data.

Fair enough - and good point, but looking over 60s is quite along time! My garmin rHR is often 10 bpm higher than a level I can regularly observe

Yes, that's the reason they have some algorithm for that. No idea what it is and what improvements they did, but taking just the lowest will cause issues.

I sometimes also think that the RHR seems kind of high, but as long as it is consistent the trends are that matter to me.

The new algorithm seems to more accurately depict a lower RHR for me.

Garmin has significantly changed RHR starting from 8.09 firmware (or 8.20 if you're not on beta). I have three different sources Garmin / Oura / Withings, so I put together the data to validate the difference between/after. Here is a post in my blog if one is interrested - https://quantify.d.pupkov.com/why-we-shouldnt-trust-any-aggregated-metrics-in-quantifiedyourself-world-d1daf90c042?source=friends_link&sk=ca064c6f95323b7314d173af85628fb7

To be honest - I'm not happy that such an important changes are made without proper explanation from Garmin marketing team.

Yes, it should be known how that is done.

They have this page: https://support.garmin.com/en-US/?faq=F8YKCB4CJd5PG0DR9ICV3A

But as they now made improvements and numbers differs it kind of would need explanation and at least on your case it's not matching the other sources so it seems to be out of line.
