It can fluctuate on a year-to-year scale, but you are not going to notice unless you have several hundred thousand $$ to spend on some very expensive
and very sensitive equipment. The difference even over several years is way out in decimal point land of a percent. Your day-to-day difference in
body weight (for example before and after using the toilet) will have an exponentially greater effect.
