Confused about adjustments in myfitnesspal?

Hi, I just bought a Flex yesterday and I have not owned a fitbit before so there are a few things I'm not too clear on. I have been logging my food in myfitnesspal for a long time now so I successfully synced that with the flex, but I'm not sure what to do about exercise. Normally I would go to the MFP app and add "brisk walk 3.5 mph" (my typical exercise) and the amount of time and it would say how many calories I burned. So today I went for a 16 minute brisk walk wearing my fitbit and it showed as "moderately active" time, which was all well and good. But in the myfitnesspal app it showed my "fitbit adjustments" as being 25 calories and I know I burned more calories than that- I thought it would show as 50-60 calories. I also thought it would add calories burned from my daily non-exercise activity, just walking around the house and so on. Can someone explain how these adjustments work?

It is all a bit mysterious!

My understanding is that both fitbit and MFP have an estimate of the calories you are likely to burn during the day. If your calorie burn as recorded in fitbit goes above that estimate then it sends an adjustment to MFP that is the increase beyond the expectation.

There is a setting in MFP (that is off by default) that also enables negative adjustments. Here, when your effort goes below expectation it sends a negative adjustment.

For all this to work it is important that your profiles and goals are set the same in fitbit and MFP.

As for logging exercise, you should be able to log it in either fitbit or MFP but I fund it simpler to use MFP just for logging food and fitbit just for logging activity.
