How is the HRV 7 day average calculated?

Hello, can someone tell me how the 7day HRV Average is calculated. I try to comprehend this value of 49, but I don't get it!

If I add the last 7 night values and divide it by 7 it's not Garmins value...

Surprised? Garmin have their own values, and they are not often in line with the real world.

HRV , i am 100% sure that the algorythm has been changed in the last update .

But don’t expect any meaningfull…

I agree and believe there must be changes since the last update. I was never unbalanced, since the last update I'm unbalanced, starting the next day/over night after the update, now I'm since 16 days unbalanced. Personal I don't feel any changes in my healthy!

I noticed gaps in the HRV graph under the sleep data. I also had unbalanced due to higher HRV. Noticed that sensor lights were dim and didn't go to normal brightness. Restarted the watch and it's back to normal without the HRV graph gaps.
