I have a possibly related issue with sleep time in the last few days (probably since updating the Fitbit app in late September). I have the sleep sensitivity setting set to "Sensitive". In the past, this resulted in the reported sleep time being Total time in bed minus waking time minus restless time. This typically resulted in about 5 1/2 hours of "time asleep", and I had set my goal based on this "sleeping soundly" approach. After updating in late September, even though I've made no settings changes, the app now reports more like 8 hours of "time asleep", which is apparently Total time in bed minus waking time. If this is a change you made intentionally, please note that at least one user doesn't like the change and consider changing it back. If unintentional, please correct it.
