There should be random spot checks. Just grab a bag, weigh the contents, eat it. Like 50/year, or whatever N is required for certainty. Is the mean at 0 deviation, or is it low, or high? Then fines collected for the deviations, but only if they don’t average to zero. Only if they’re tilted.
Hopefully it’s got to average. If they’re cutting 2% off all the time that’s no good
That’s probably what they’re trying to do. The better their quality management is the closer to consistently packing -1.95% they’ll be.
