The sleep score is calculated on the actual duration of sleep and not the time spent trying to sleep in a bed. I finnaly understand why, but the fact is that we can not change our score easly, the only think we can change is our time to go to bed and to be able to adjust this choise it’s important to know the time we spend in bed and the time we really slept and this information is not clearly write in Sleep As Android.
Moreover, I imagine that the majority of sources that give a recommended sleep time are calculated not on the actual duration of sleep but on the felt duration that we could define as the time when we feel that we have actually fallen asleep until the time we woke up in the morning (“actually” because we are all aware of having spent 20 minutes trying to sleep for example and we can easily remove these 20 minutes from our sleep time). Until recently there was no application that allowed us to count the time awake during the night except in the case of real and visible major insomnia. I therefore have a lot of trouble understanding how this sleep time can be calculated by removing micro sleeps and ultimately in my opinion move far away from the recommendation or the sleep time that the majority of people express. If I ask my friends how long they sleep they will tell me: Well I sleep from 11:30 p.m. to 7:30 a.m. so 8h possibly we remove the 20 min to fall asleep so 7h40 of sleep there are only people who would have a sleep tracking application who could calculate their real sleep time but again I don’t think that it is the majority and therefore the time most often expressed.
For all these reasons I think that the time spent in bed between the first sleep and the last awakening should be clearly indicated in the application without having to do a calculation.
