Fitbit Sync Issue

I've had my Fitbit since Christmas and most days it syncs nearly every time I log into MFP, as long as I've been on my Fitbit app first.

There have been some days where it hasn't sync'd until later in the day but I just keep an eye on my calorie burn on the app & make sure I'm under on here.

You won't get a calorie adjustment until you have exceeded the activity level you have MFP set up for. I have to be over 4000 steps before I get any adjustment set at sedentary here if that's any guide, although it may differ according to your weight.

It will rise and fall across the day once you've got an adjustment. For instance you could have 200 extra cals at teatime but a lazy evening may see those drop significantly because it calculates based on the assumption that you will remain just as active for the rest of the day.

When, or how often, is fitbit supposed to sync over to myfitnesspal? I do understand there are issues being worked out. I am just curious how it is supposed to work, so I know if I am, in fact, even having a problem. I am new to fitbit as of today.

I think I read somewhere that fitbit tries to sync every 8 minutes or so. I have noticed sometimes it takes longer but not much.
