Method: time awake in bed = time to fall asleep + waking in the night + time in bed after waking for the day. Time asleep = time in bed - time awake, and sleep efficiency = time asleep / time in bed, as a percentage. It uses averages, so differences between nights do not show. It is arithmetic on your diary, not a clinical assessment.
