If I wear my Fitbit One on a treadmill or elliptical, should I log the activity as well?
The FitBit Activity Tracker (on the website, Android application, and I would presume the iPhone application as well) lets you log various activities so you can track and share them with your friends. You can explicitly log things like running, using a treadmill or elliptical, or other activities that would also cause the device to count steps and miles. The device (and the website) also track your calories burned based on your profile, and when you track activities, it also estimates the calories burned based on the type, duration, and other parameters of the activity.
I've been trying to determine how exactly FitBit uses the activity tracker data. Does it convert miles run to steps (meaning wearing my FitBit when tracking a treadmill activity would cause double counting)? Or perhaps is the device smart enough, based on the start time of the activity, to not double count? Or are the things like distance, time, and calories burned in the activity not totaled with your device data?
I'm mainly concerned with the things tracked by the device: steps, flights of stairs, miles, and calories burned. At the end of the day, I'd like at least a reasonable estimate of these things.
I couldn't find anything in the FitBit FAQs as to what is recommended, nor many discussions on how others deal with this.
Which specific model do you have? I believe the different models use different sensors, which could affect the answer.
@IvoFlipse I mentioned in my title that I have a FitBit One. Based on Kate's answer, it appears that the One and the Ultra behave the same, so I'm not entirely sure the model is relevant to how the website deals with data being entered through it (or an app) and from a device sync.
I must have Read over it. I thought I read the Ultra uses a barometric sensor, which probably wouldn't be useful on a treadmill. However, it seems it also has an accelerometer, which should be capable of detecting running on a treadmill

Here's how I do do it (I have a fitbit one).
When I'm doing an activity that I think the fitbit won't track properly (biking, or a sport), I switch to recording/sleep mode (they're the same). I only do this so that I can remember how long that activity took.
Then, using the web interface later, I enter the actual activity, time, and duration (using info from my recording mode to have accurate start/stop times).
The activity section of the manual says "All steps and calories recorded by your tracker are overridden for the duration of a manually logged activity by the activity's entered values. This ensures that your steps are not counted twice as long as the manually logged activity has the correct start time and duration."
Do you think that a treadmill would be tracked properly? Or if you use a treadmill, do you use recording mode? It seems pretty close to running.
I don't use a treadmill, but because the fitbit is based on a pedometer, it should be able to track treadmill steps and distance as accurately as it would outdoor running.
I found somebody else's testimonial: https://www.myfitnesspal.com/topics/show/684979-fitbit-v-treadmill Looks like steps and distance are pretty accurate, and calorie count might be even better estimated by the fitbit than the treadmill.
In my experience, it tracks steps on a treadmill pretty well. But actual distance is tracked pretty terrible. I guess this might depend on how long steps / kind of stride you use on the treadmill. I'm in terrible shape (extremely obese) and guess I have a completely different stride than some of you guys.
Great answer, for activities with a lot of step-type movement I rarely find it necessary to use recording mode. When I play ultimate frisbee I just look at the graph and I know when it began and ended within 5 minutes because that's when I stopped moving. (Hell, you can even tell when the games end and we stop for a water break.)
