I understand that, but at the end of the day you had a large amount in 1985 and in 1995, but in 2005 it was lower. What am I supposed to extrapolate for 2015 from the same thing? Is it going to be 65,000 or 60,000 tonnes because the exploitation rate has gone up? I'm getting concerned here that we're going to be seeing a decline in peak every ten years, as opposed to a cyclical stock.
