so every time i measure it *may* be off anywhere from 0-3% or greater? or is it a flat rate of +3% every time?
i.e. jan 15 i measure 12% BF. jan 16 15% BF. jan 17 14% BF ?
or, assuming my true BF is 12%,
could i measure out the same inaccurate +3% figure for 3 days in a row i.e. 15%/15%/15% assuming diet doesnt change?
i can deal with something that will give me +3% every time i measure. but if it changes every time i measure.......that is a problem.
see what i mean?
