*this is a re-post because I clicked accept solution by mistake* I like everything about Fitbit except the way it calculates time spent asleep. Since 10 or 20 pc is normal “awake” time during the sleep cycle this time should be part of time spent “asleep.” When a doctor or researcher recommends 8 hours of sleep, I believe they mean sleep from, say, 10 pm to 6 am. They do not mean sleep for 9.4 hours because 15 percent is going to be deducted. It’s frustrating getting numbers that make it seem like I’m sleep deficient when I’m really not. For instance if I sleep 8 hours, Fitbit says something like 6. At best, if I want to discuss my sleeping habits with my doctor, I’d have to do a conversion which is inconvenient.
