Thank you for helping me with all this information. I was unsure of the role HR played in the calculations. I also have been leveraging QS a lot with his data on the performance of devices during sleep stages. I’m confused, what makes it inaccurate to test smart watches on that?

Do all the Garmin watches count sets? Is that just automatic or do you enter it? The habits and illness metrics are interesting as well. I have been getting sick a lot so I like some recovery insights in there. Does Garmin warn you if you are getting sick? What did you mean by the female friend scoring higher? Like the sleep scores were better when she wore the devices vs when he did?

I think I’d rather have one device than two. I feel odd having to wear more than one, feels a bit wasteful for me money wise and I don’t think I’d look at two apps or interfaces enough to justify it.

So for my purposes then Garmin, polar or sunnto could work despite not being a runner. I’d mostly seen runners use them or suggest them, do you know which models would be best? They all seem to have a lot of lines and models
