That being said, you hit the nail on the head with something I was thinking and what an average Canadian might think as well, which is that I'd rather have more than not enough and then deal with managing it after the fact, to ensure that safety is the top priority.
Is there an international convention on what the acceptable margin of waste or expired materials is? Do we know if we're in line with what other countries were dealing with?
