Maybe I will then. I just assume that the technology to accurately determine REM vs Deep or Light sleep is not really available, so I can't fault Fitbit or any manufacturer for not having perfect sleep trackers. But, the marketing material does claim it's very accurate, so I should probably get more out of it since that's what I was sold. Thanks for the advice.
