When you are entering your info for your elliptical, are you changing the numbers? When I entered your exact info (time, speed, etc), it showed I burned 230 calories, and yours says 126. It's not a huge difference, but I also showed that I did 3.93 mph, and yours shows 4. Is this data the tracker is calculating for you, or are you entering your own?
If you are entering your own, then it seems that you've already figured out how to change the calories, correct?
