If I am on call, and have to get up to do some work after sleeping 4 hours, then go back to sleep it only seems to count the 4 hours or 2-3 hours sleep, not the total amount. Same with taking a nap, it just does not count it. How can I trust the body battery, or recovery information, if the software can not even keep up with my total sleep time. I have a Garmin Epix Pro Gen 2 47mm.
