Sleep Data - When Do I Need Them the Most?

i've been using auto sleep a and the ap does a lot of things with regard to sleep, but the only thing i care about really is what it does. When i need the sleep data the least is when i'm able to record it the most. I know of your wear mike, but that guy is pretty good for recommending things. E i live a lot of my life faced upon the recommendations he gives mey i've been usingauto sleep a andthe ap does a very good job of estimating just the length that i was asleep, when did i go to bed and when did i wake up.
