BodyMedia Fit Link- Calorie Input

I just started using the BMF Link and have input my calories using MFP, but I also failed to input extra calories from a "cheat" and didn't have any clue as to what they were as it was one of those "make your own" froyo places. If I input my weight in a week, or whenever, and it isn't the weight loss it should've been, does BFM Link recalculate calorie burn? I don't want it to mess up my calorie burn estimates, etc. Hope this makes sense ;)

Thanks!
