After logging exercise, calorie count goes down??

[JCAB]

I manually logged 2 hours of skiing activity today, and immediately the total calorie count went down by about 200 calories.

This is confusing. The app sends to be replacing all calorie s calculated via measurements with a lower flat rate for the 2 hours.

Could I be doing something wrong, or is the app so flawed?

That is exactly what it is doing.  Manually logging an activity after the fact is meant for times when you were not wearing the tracker.  It overwrites all recorded data with whatever parameters you input for the activity.  If you want to go back to correct daily totals, just delete the logged activity, unless it is more important to have the record that you were skiing.

But that's completely counterintuitive! I get that the app can have some heuristic for filling in the blanks, and that the logged exercise can modify those synthetic readings. But the tracker had already provided data for the time period. Wiping it out (or hiding it) serves no purpose I can possibly think of. And the app doesn't give any indication that the existing data will be ignored or overwritten in this way.

I'm not arguing with you.  I'm just explaining that's the way it is, so now you know.

@JCABWe get peaks and troughs in our exercise and when you manually log an exercise it "flatlines" the calories over time., or averages the calories and most times it negates the Active minutes. This link explains for another user.

Depending on your Fitbit I use Workout and then rename the activity, or just use the the Activity Record in the Activity log on the PC. with the example in the link..

@JCAB .. I would take the advise offered by @Colinm39 . Start the activity as something you already have in your list of exercise. That way you capture the data you are looking for. Later, if you absolutely need to know that you were skiing, you can edit the name.
