In this case you really do have to get the system absolutely perfect, not just good. It is unacceptable for someone to receive a bottle that contains any amount of dirt or other contaminant.
I'm not an expert in this so idk how difficult it is to ensure this but unless the system is perfect it can't be used.

- TeMPOraL 7y agoYou don't have to make the system perfect. You have to make it cautious. At any time it suspects a bottle may be too dirty or not getting cleaned for some reason, it should reroute it to manual inspection line and/or straight to remelting. So now you lose 30% of your yield, but the rest is clean and sterile. That's a good starting state, from which then you can optimize the contaminant detection.
