You show it recording hrv during rest which is the easiest time to record hrv which is not the same as hrv when not at rest. [/quote]
I showed what I showed. Thus, you can decide if that’s enough or if you need something beyond that. The overwhelming vast majority of 3rd party HRV-uses today are at rest, not during workout. My wording is very specific in what I showed, and what I specify: Is it sending valid data? I don’t try and figure out if it’s accurate data or not, I try and figure out if it’s sending valid per the spec.
In fact, this seems like a fun time for memory lane. Because - ultimately, the singular reason that data field is there in the product comparison database, was a request by yourself from years ago to add it. Thus, I added it, then spending the time validating whether or not the data exists (because back then, it didn’t exist across the board). I’ve never said, nor attempted to say whether it’s accurate - because frankly, I see poor HRV accuracy agreement across any straps. I think it’s highly questioanble. I’ve focused purely on the underlying BPM values (and hence a specific accuracy section), not HRV values. There’s some interesting HRV science, but there’s also a crapton of Bro Science in HRV too.
But I like your thinking - I’ll remove it across the board from the product comparison database.
I’m unclear why you’re talking about me talking about breathing rate. I didn’t say anything about breathing rate. Nor do I ever compare accuracy in breathing rate.
