It really has nothing to do with Phil but as Lugnut said that its a theorem and that's all.
Regardless what people want to think, knowing past performance of freight-lanes is no real guarantee of present freight revenue unless one wants to step out of the box and think beyond the "expedite" thing.
There is a governing factor involved with all of this, your carrier. If your carrier is not actively looking for freight to move trucks, but rather looking to capture top dollar revenue, then you will sit anywhere you land. AND with that, you as a contractor DO not have the right information to make this little spreadsheet useful, even at LS.
