why not allow more detailed editing of "sleep"? Too often it happens that the clock marks parts of the night as being awake, even though they weren't! Sometimes it is not possible to maintain a perfect position and tight watch all night long...
I also have this issue but in reverse. My watch insists I was asleep when I was awake. Not sure how to fix this.
the only solution would be the possibility to edit all elements of "sleep", not just the beginning and the end...
