Put an RP 440 with 6 each 8 quart stainless cups next to your machine or oven. Set the counter to the number of parts you wish in each cup and start producing parts. Inspectors can check if parts are to spec in each cup.
If the parts have gone out of spec, you dont have to throw all the parts out.
Check and find out which cups have good parts and throw the out of spec parts away.
