Some important notes 📝(!):
(1) WHOOP will be rescored with the new algorithm, and the preprint updated once that is done (i.e. WHOOP will likely improve)
(2) Google/Fitbit is based on their old algorithm. Unfortunately, they couldn't rescore it.
(3) There are still some errors in the text: important, Garmin Vivoactive 6 should (I believe) be Garmin Vivoactive 5
(4) This is a preprint, and it hasn't gone through peer review yet!
(5) I am a co-author, and was mostly involved in the setup of the study and data extraction. All the formal analyses and practicals were done by Pavlos and also Laurin
(6) My conflicts of interests (affiliate links) still need to be added.
