Sleep tracking reliability

How many times does your fitbit say you were awake and restless on a given night?
I know it over estimates my sleep, but am curious about the rest. (no pun intended)

I'm getting the Alta soon (zip currently ), so would like to see the answers too.0

It varies. I take the sleep tracking with a grain of salt, although most of the time if I feel like I got a good night's sleep, my stats do reflect that, so it can be used in a relative fashion - determine what is normal for you and then work from that point. For me, I find that if my sleep efficiency is above 90% (this number, as far as I can tell, is only available on the website, not the mobile app) then I feel fairly well rested. My goal is 7 hours of sleep (as measured by my Fitbit), but I typically get between 6 and 7. Less than 6 hours and I'm dragging. More than 6 hours, but with a sleep efficiency of <90%, and I'm dragging. Unfortunately, sleep is a lot harder to control than steps, exercise and food, so increasing my sleep time and quality has been tough.0

Thanks Nancy. I find mine overestimates, I think. I can know I've just laid there for hours, but, (logically, I guess) the fitbit says I slept. For example for Wednesday night it says I was awake 5times, restless 26 times, awake/restless 1hr and 20 minutes, but I KNOW it was much longer than that.
And yes, sleep is much harder to control than steps!
thanks for the replies.0 -
Over estimates my awake time, I think. Spot on how long I am in bed, though.0

I find that it has trouble detecting when I actually went to bed but is pretty good about knowing when I woke up. So, I try to note when I get into bed at night so that I can go back and edit the record in the morning. That way, I can get a more accurate "time to fall asleep" number. Interestingly, it also usually ends up calculating a little bit less sleep, even though the "went to bed" time is earlier. For instance, for last night, I adjusted the time I went to bed to 10 minutes earlier and my "actual sleep time" went down by 12 minutes. My sleep efficiency went up from 92% to 95%, though.0

I'm not sure I don't really pay attention to it.0
