Another "How accurate is this?"
Wearing the watch full time for a week. My dog got me up at 4 am to do her business (not normal!) I jumped up, threw on clothes and went outside.
It's a 75 foot walk to front yard potty area. We were outside 15 minutes, walking around while the trots get blown out....
Go in, and miraculously get back to sleep.
My sleep monitor showed restful sleep, with no motions during that time! WTF? really?
I love my new watch, but damn, when something is that wrong, how can there be any correlation to what REALLY is happening?
