Fitbit calorie adjustment issue

space_case

So, I am confused. I didn't work out yesterday or the day before so both days show on fitbit zero active minutes. Two days ago Fitbit said I burned 2347 and yesterday 2346, but my UA adjustment from on MFP was 250 calories less. How the heck is that possible? I tried synching and resycncing and nothing changes. The difference in steps was about 400/.1 mi.

I should add I tend not to eat back calories especially on days I don't work out, but it would be nice to know that even if not 100% accurate, the numbers are consistent.

Fitbit algorithms calculate using averages over time; that is why people say they "learn" from your habits. You may have just experienced one of the days that a particularly highly active day in the past dropped out of the rolling average and the Fitbit algorithm adjusted the current Calories down.
