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.

They are both imprecise AND inaccurate?

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.

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.
