@VoiGAS This is also my main interest. I’m curious if the ZS data is “cleaner” at all, perhaps less chaotic in the high/low swings, or more “accurate” for time spent in each zone. I see a lot of noise when I look at the DFA data in Runalyze and have always been curious if the strap or my shirt is creating ESD that’s messing up the HRV data.
I’m kind of “meh” about ZoneSense right now with my Polar H10, so if there is cleaner QRS data at the module before reaching the watch, which in turn leads to less noisy DFA data in Runalyze and less noisy ZS charts, I’m interested.
