my wii is no longer accurate.....

vsetter

....is there a way to re-calibrate the wii fit board?? It has always been pretty close to my personal scale, and now it seems to be off by 3/4 lb or so. My personal scale at home is a doctor's scale and is already calibrated correctly, so I figure it is the wii board that is off target.

Any quick fixes or do I just deal with it????

Naturally, it is adding 3/4 lb....or I wouldn't care as much
