alt Hacker NewsFor me the value of Garmin (Forerunner) is their proprietary algorithm for calculating Stress Level from HRV. It is the basis for the Body Battery measure. I find it useful to see how food and activity affects my stress levels.
I guess it would be possible to reverse engineer a similar stress level calculation. Perhaps AI-powered?

If the algorithm is proprietary, how do you know it is calculating something meaningful?

HRV from optical is garbage-in garbage-out
and post-2020 Garmin has totally lost their way with development/algorithms

Yes, and the sleep tracking that adds or subtracts. While not super accurate, it's good enough for me.
I'm not sure the body battery/stress measures are that great. Garmin is infamous for having an awful sleep algo and it still has a lot of trouble detecting naps. It doesn't bode well for being able to get stress data. I think it's good for generally determining high stress vs low stress and when you've overdone exercise recently but probably not much more.
