Isn't it a well-known fact that Garmin has terrible sleep tracking? The wearables can't handle deep sleep at all; even Muse with EEG can't reliably predict it, so I wouldn't be drawing conclusions here.

A small curiosity: I recently learned that sleep trackers in commercial wearables are terrible for people with sleep disorders like apneas, UARS, etc. It makes sense, as this isn't a typical dataset, but it's worth knowing.
