Another puzzled MyFitnessPal user - Diary calories very unpredictable

[OrpheusExultant]

I'm a long time user of both my Fitbit One and MyFitnessPal.  Lost 30 lbs over the past three years, so thanks both!

I have linked them.  I use only MFP to track food and calories.  I have no other exercise plan than my daily steps.  Both are also linked to my Withings scale, but I don't think that will factor into my problem.

Hitting my 10,000 steps has always meant about 300-400 Exercise calories.  But lately, I cannot find any logic to it.  My last five days look like this:

Nov 13:  Walked 13,933 steps - MFP says I have 189 calories Exercise

Nov 12:  Walked 22,264 steps - MFP says I have 461 calories Exercise

Nov 11:  Walked 9,074 steps   - MFP says I have   17 calories Exercise

Nov 10:  Walked 12,014 steps - MFP says I have 281 calories Exercise

Nov   9:  Walked 3,940 steps   - MFP says I have   97 calories Exercise

Is something broken?  Is there some weird reverberation between them, where they update each other, then update each other based on the updates?

@OrpheusExultant Welcome to Fitbit Community!  Let me help you with this situation. I'd like to start by asking some leading questions to figure out what's going on and determine the root cause of this issue:

- Have you tried to unlink and relink both MyFitnessPal account and your Fitbit account?

- Do you already know how the "Fitbit Calorie Adjustment" work? Calories sync from your Fitbit account to MFP. When there is a difference in calorie estimations between Fitbit and MFP, MFP makes a "Fitbit Calorie Adjustment". The adjustment represents calories burned above MFP's estimate and will update each time Fitbit syncs. A negative adjustment will occur if you're less active than expected.

Let me know if you've already tried to re-link both accounts. If that doesn't work, follow-up with me.
