The first thing I would point out to you is that margin does not equal profit. When you see a refinery margin, whether it be 10¢ or 20¢, that is just a simple calculation of the difference between the wholesale price and the crude inputs.
What I'm telling you is that our profits are averaging about 1.5¢ a litre. The margin may be high, but at a given point in time, the margin also may very well be low. As it shows on the graph there, it is actually very volatile. But at the end of the day, I think what is most important, from people's point of view, in the context of what is a reasonable profit is really the question of the 1.5¢ a litre, not the volatility in the margin.
Do you want to add something, Dane?
