What the heck are you talking about? The only flexure to speak of is within the load cell itself and... Can you even call that a flexure? It's a teeny tiny strain gauge mounted on a piece of steel that's going to bend ever so slightly when a weight is put on it. Even the cheapest load cells are precision-manufactured well within the tolerances necessary for the strain gauge to give you damned accurate results. I've never seen a human weight scale that went beyond a single decimal place and in all honestly they're going to be very accurate. If you get on the scale and it says 201.2lbs that measurement is going to be accurate within ±0.1lbs (actually, more than that but you only get one decimal point of precision). If you put the scale next to something that's emitting a ton of electrical noise then maybe it'll be off by 0.2lbs but I doubt it.
