I manually started a GPS tracked Walk Activity at 10:49am that lasted for 5minutes. My heartrate was in the cardio zone over most of the Walk. After stopping the activity when I arrived at my destination (my apartment entrance), I spent the next twenty minutes or so doing household chores that kept my heartrate elevated. There were over 1000 steps recorded by the Fitbit during this time. Fitbit Auto-Exercise Recognition logged the chores as a Walk Activity. I'm fine with this. What I'm not fine with is the auto-recognized activity started at 10:50am, including 4minutes of the manually recorded Walk Activity. By doing so the Fitbit is doublecounting steps, calories and active minutes. I went back through my activity log on the Fitbit.com dashboard for the last month, and found that most of the Automatically logged activities include time that was already part of an activity being manually recorded.
The obvious fix for this is to disable auto-exercise recognition. But the Fitbit should be smart enough to know that if an activity is already being logged, the time from it should not be included in the Auto-Recognized Activity.
