not everyone falls asleep right when they decide to and sleeps through the night. it often takes me several hours to fall asleep, and I tend to wake up several times throughout the night. The app ends up counting all of that as time asleep, so it ends up being very inaccurate about how much sleep deficit I have. On the sleep tracking graph the time awake usually shows up as light sleep, but that is not what it is.
