Do recovery scores from wearables even make sense?
So I've been tracking my sleep with a few different devices, Apple Watch, Whoop, and Fitbit, and honestly, the recovery scores feel like a game of darts. One night I get a 'great recovery' on one, while another says 'needs improvement.' Are these devices just throwing numbers at me? I could really use a good night's sleep and some clarity here. Anyone else feel like they're just guessing?
