I've noticed, that floors climbed credit is frequently too high. Fortunately there's a reason, given in Garmin's FAQ, that is very reasonable:
Walking into a warm building on a cold day or even walking near exit doors when it is cold outside may trigger excessive credit.

And yes, this has place in my case. Outside there's -1 to 0 degrees Celsius, and in the building it's 15 degrees C. And it's reasonable, that it may be an error on calculations in this case.
Well, how can I deal with it? Could I minimize this erroneous deviation?
Can this problem be resolved by calibrating barometer via GPS inside of the warm building?
Should I calibrate barometer outside via GPS, when the pressure (or temperature) outside will be higher?
