The model's prediction: copper production would rise if the mill were fed more ore per minute. Veterans of the trade had initially resisted the idea of running the mill faster. They wanted to keep the stockpile of ore from dropping below an established minimum, fearing that if the stockpile were too small, the mill's performance would suffer.
