The truth is, all the rules re: when to code out time are arbitrary. Do you need nutrients in order to stay hydrated? Of course. Drinking water is not sufficient. The company has made a bureaucratic mess out of it because it is obsessed with not just profits, but also the production numbers themselves ... an obsession which, of course, costs them quite a bit on the back end and that, I'd be willing bet, they really cannot calculate. The company's perspective is reactive and short-term. They quickly forget to do the difficult work to implement and maintain their "longer-term" plans, e.g., ORION.
