I don't think I understood your point. Are you agreeing with me or disagreeing?

Not sure which world it will be :o), but here are some links on TE:

What makes you think that the TEed route between the CN and the MN
(i.e. Chicago -> Miami -> Dallas) will be a slow path?
Do you think the shortest path is ALWAYS the best/fastest path?
