It has implications for that.
The other part we haven't talked about in terms of the product side is of course the crude slate. We often want to talk about crude as a single type of product. Well, there are multiple different types of crude in terms of their weight, their heaviness, their sulphur content. So refineries are also configured generally to refine a specific type of crude. That is one of the economic challenges of balancing. What I would call heavier, more sour crudes are generally less expensive on the market. So you can get your feed stock at a lower cost, but in order to make that into the product mix you need to make, you need to have a more complex refinery, and your refining costs are higher. It's always that delicate balance of feedstock, refinery configuration, and managing costs. Then you have to match those with the demand profile, whether it emphasizes diesel, aviation fuel, or crude. Then you have to meet all of those aspects around seasonality.
So when Mr. Corey defined a very simplified refinery, that really masked much of the complexity that's involved in the refining business that relates to crude, processes, and ultimately final products, bearing in mind the seasonality issue.
