At the end of the day, it gives an estimate of what your weight will be in 5 weeks based on that days calories and exercise (i.e. net consumed after exercise). I never eat the same amount of calories a day and my exercise varies depending on the day too.
I never look ahead 5 weeks as it seems SO far away to me. But now I marked my calendar to see if it works out. (It says by March 7th I will be 213lbs which seems a bit of a reach but we'll see!)
I'd ask on MFP but their site isn't as good as this one.
