The real answer is that bathroom scales have god awful precision and accuracy.
Most mid market scales buffer the weight to normalize it. I got a $20 one off Amazon that just tells me fresh every time and it’s great. I pooped .4lbs this morning.
Good job
Hmm, how would they buffer it, if you've got multiple household members? Or are we talking about those weird scales that require an app?
If last measurement within half a pound, show previous measurement.
They are both imprecise AND inaccurate?
When talking about measurements, "precision" and "accuracy" have slightly different meanings See here
Most digital bathroom scales will repeat your last measurement if it hasn't changed by more than half a pound. I pick up a 1 lb soap bottle off the counter first, then measure again without it for my weigh in.
Customers really hate seeing if a scale has a little inaccuracy in back to back measurements, so they all build in this bullshitting.
so you're saying we should invest in an industrial freight shipping scale for maximum accuracy
I love this. It remind me of the whole South Korean fan thing.
I'm short-sighted and on our mechanical scale, I can't see the thin lines to count out the precise kilos.
At first, I was bothered by that, but yeah, in addition to natural weight fluctuations, just bouncing a bit on the scale would stop it at different kilos, so eventually I considered it more of a feature that I couldn't tell precisely.
