@1plustriplets If your tracker measures floors, it detects floors using an altimeter, which is a sensor that calculates altitude based on atmospheric pressure. Though your tracker is designed to look for pressure changes based on elevation gains, pressure changes due to other causes—such as a gust of wind, a weather change, or opening a door—can occasionally cause your tracker to register an extra floor or two. Another factor is floor height. Your tracker registers one floor when you’ve gone up about ten feet, which is the average between residential and commercial floor heights. If you climb long staircases you may find that the tracker’s floor count doesn’t match how many floors you’ve gone up since the staircase was taller than ten feet.
As for floors, Fitbit trackers have a finely tuned algorithm for step counting. The algorithm is designed to look for intensity and motion patterns that are most indicative of people walking and running. When working at a desk, cooking, or doing other arm movements, a tracker on your wrist can pick up some extra steps if it thinks you're walking. Many of these situations—such as working or cooking—do include a few steps in-between stationary periods so the tracker tries to give you credit for those steps. For the vast majority of customers, the amount of stray steps accumulated is negligible when compared to the entire day.
If this extra activity continues to show up, keep me posted.
