I know this sounds crazy, irreverent and un-american but...  well,
I'll admit it: I've been waiting for more data.  With only 4-6 games
per team, I don't think that the results are meaningful.

But hell, after such a compliment, how can I not post them?  Here we go:

Explanations: Only div-I-A games are taken into account.  Three points
home advantage, 20 points maximum blowout, and a 10 point bonus for a
win.  (this means that a 3 point win is worth 2 more than a 1 point
win, but a 1 point win is worth 12 more than a 1 point loss.  I
believe that this makes sense.)  The "contribution" of each game to
the final ranking is also given.

For example, in the Washington line we see "AzSt-5.0" -- this means
that Washington's 24 point road win at Arizona State seems to the
algorith "too mild" -- its is actually pulling Washington down!  On
the other hand, the "Nebr+5.1" says that the 15 point home win over
Nebraska is pushing the Huskies up.  Well, that's life in the computer
ranking game.

So *please* don't ask me why FSU is ahead of Miami, and why Kansas is
ahead of Cal.  You can look at the numbers and see that those games
represent a big "error".  The algorithm just has a lot of other
constraints to satisfy, and this is the best it can do.  Forgive the
algorithm, for it knows not what it's doing.

(By the way, you may also infer that in the opinion of this algorithm,
the biggest upset of the season was Purdue's win over Cal: an error of
21.1!)
