HRV 7 day average incorrect

Thanks for the reply! However it seems that I can’t access the link that you shared, it leads to some internal support site. Could you please check?

Thank you for bring this to our attention, here is the corrected link: What Kind of Data Is Impacted by or Impacts HRV? 

Hello Katze, I just want to add a +1 to your case.

My 7d Average HRV is ~7 points below my manually calculated value. I am using the last 7d overnight sleep HRV to calculate it. 

This issue has high impact since Garmin uses the average HRV value for many other metrics. I am wearing a Forerunner 955

Thanks for the link, I’m familiar with this article, however it does not have the info how is the 7 day average calculated. Also, if the average is not an actual average, then naming it that way is misleading.
