Compute total sleep efficiency in addition to deep sleep.

Petr, Sleep Efficiency is rather simple to calculate as it's a percentage based on time slept, how many times you wake up and how long for and how long it took to fall asleep again.

The following site explains the concept and how to do the calculations in the section marked "Measure Your Sleep Efficiency"

This is a rather standard calculation in the field of Sleep Assessment so don't worry about it being a Dr Oz article, the information is still correct. I just wanted to let you have an example laid out fully.

If you want to discuss more I'm contactable at

i thougjt about it too. In my case has to do with deep sleep length, awake periofs and time needed to fall asleep…
example: a good sleep for me would have at the same time 8 h length, just 4 deep sleep cycles , each around 1.5h and awake almost zero (close to being awake but not awake)
These parameters could be sugested by the app based on rating or manually entered by user
