I certainly can't do the math, so, yes, it's complicated. We have a team of economists at the agency who do that. As Randy said, it does become an exercise in art, not science, because what you're trying to do is to determine that sweet spot of distance whereby the maximum amount of carriage has access to competitive line rates. Again there's no absolute cut-off point where our data showed that after this distance demand drops off entirely. I think it's going to be the usage and the anecdotal evidence about what the shippers and railways are telling us about what it's done to the negotiating climate that is ultimately going to solve that question. There's no substitute for time.
