Eddie, you're missing my point. I do better at home on my good and so-so teams and worse with my weak team. What I'm saying is I think there might be an advantage for the visitors built in to counteract the natural advantage of a human manager. My better teams still overcome it and my weak team can't , but most teams will still do better at home.
So calm down Casey, you're better at home because of the advantage we all enjoy, not your shining genius. :)
