My Index Sleep Monitor seems to assume I'm asleep right when I put it on. For example, last night I know I fell asleep sometime after 10:18pm. I put the monitor on at 9:55; it has me at 5 mins of light sleep immediately, followed by deep sleep. I was lying there (admittedly, quite still) reading a book until 10:18, and then it took me some time to fall asleep after I turned off my light. I see my heart rate fall on the Timeline around this time: from around 48-49 down to 44 from 10:20 to 10:32pm, which is when I suspect I was actually falling asleep. I'm on firmware 3.70. Anyone else seeing this?
