Surge counting stairs while running

[kermit315]

Hello,

I just got my surge yesterday, and am enjoying it.  I do have a question though.  It counted more than 10 flights of stairs while I was doing a treadmill run of three miles (though the fitbit measured 3.05 or 3.06 I think).  Any idea why that would happen.  I am doing a lot of stairs right now (on deployment on an aircraft carrier), but not while I am running on the treadmill.

Thanks.

Did you increase your incline on treadmill?

Usually when I run on roads, it counts stairs when my elevation increases.

Thanks,

No, incline was zero. Just ran a flat 3 miles and it counted a bunch of stairs.

Probably an atmospheric pressure change blowing through during the run.

(An incline on the treadmill wouldn't make any difference since you wouldn't actually be climbing i.e. no resulting altitude change).

My surge counts stairs both on the treadmill and on the elliptical.  Even when I choose elliptical as the exercise it counts stairs.  It should know if I choose treadmill run or elliptical that I'm not climbing stairs.  There must be a FitBit fix for this out there somewhere.

MikeF is absolutely right.  If the surge detects a pressure drop while you are doing some other exercise (or I suspect it detects a motion similar to walking) it will register the pressure change as stairs climbed.  Fitbit could disable the stair counting function when you select an exercise like treadmill run?

That could be part of it, but it happens every day without fail - treadmill, elliptical.  Unless the Surge detects the gym's air conditioning as pressure change, I'm still at a loss.  I don't think this accounts for it.
