I use a heart rate monitor which, short of calculating calories burned in an actual lab, is the most accurate way to count them, even though it is still just an estimate. My calories on the HRM is normally closer to what spark says than what machine says. When I was 247, the machine was different than the HRM & spark by over 100 calories.
So, go with the lowest estimate. If you really want to be as accurate as possoble, the best thing is a HRM.
