ah sorry - i cant link the post cos it was on a private alt, but basically over the course of 1 week i had 44m deep sleep, 5h light sleep, 2h rem sleep, 11m awake (total 8h 19m average) - and 4 friends mentioned apnea just taking one look at my chart

they said average should be 80m deep sleep, and one guy had 2 hours deep sleep lol
