I notice this problem with the active calories count in the Widget, and also in Garmin Connect.
This is an example, I go out for running very early in the morning, so, my active calories count is almost 0. So I record a run activity, that says (for example), that consumed 750 calories. When I check the active calories in the widget says somithing like 640, so, I dont know how the widget compute active calories, or why the calories in the activity are registered in the widget.
Anyone else have this problem?
