Charge 2 not accurately counting floors

[EdKwedar]

My Charge 2 was counting a ton of floors while waking at home on flat surface.  This was a one day event that did not ever happen before or since.  There was a quick moving weather front that caused extremely high wind gusts (up to 60mph). 

ChatGPT had this to say about the issue. 

Yes, rapidly changing barometric pressure can cause an altimeter to give inaccurate readings, but it does not “malfunction” in the sense of a mechanical failure. Instead, it may temporarily display incorrect altitude information due to sudden pressure changes.

Altimeters function by measuring atmospheric pressure and converting it into altitude readings. Since atmospheric pressure decreases with height, a drop in pressure can make the altimeter indicate a higher altitude than actual, while a rise in pressure can cause it to show a lower altitude.

In cases of extreme and rapid pressure changes—such as in severe weather systems, turbulence, or rapid movement through pressure gradients—the altimeter may struggle to adjust instantly, leading to momentary inaccuracies. Pilots must regularly update their altimeter settings based on local pressure readings (QNH or QFE) provided by air traffic control to maintain accurate altitude awareness.

@EdKwedar   A Fitbit altimeter is much simpler than an airplane altimeter.  A Fitbit altimeter only registers a drop in barometric pressure.  Gusty winds are one source for error.  My work building has very tight fire doors.  My Fitbit can count a floor when I open a fire door.

This is a known source for error and no cause for concern.
