What do these Totals (see the small print below the graphs: 1,335 calories and 7 hours, 1 minute) mean here? I think the 7 hours is the total time I've been awake, but what is the 1,335 calories? I thought "move" calculated more or less all calories. And surely i haven't burned 1,000 calories more than my "active" calories? What's going on here? (At the same time, I'm getting a lot less credit for my workouts . . .) Bummer.
