Length excluding Wake times (Cloud, API)


I like Sleep as Android and have been using it for two weeks now!
As I was using the sleep-cloud I noticed the Length is calculated based on From - To times. Wouldn’t it be better if the Wake times were excluded from the total? As it is in the Detailed view of the day.

This is also happening in the API fetching the sleeps node data. If the wake times were excluded from the total, won’t it be more accurate?

Thank you
