I've been using this app for a week, and then I record my calories burned in MFP under the notes. So I've started noticing that the calories keep changing, on days that are already over. Like this morning I checked yesterday's total burn and recorded it and then went back and looked at the previous days and Sunday-Tuesdays calories burned had also changed. And it changes anywhere from 50-300 calories, so I definitely feel like i shouldn't depend on it for an accurate reading of how many calories I'm burning.

Has anyone else had this issue, or does anyone know why it does that?
