Understanding Sagarin (and other computer polls, I suppose)

Help me understand this:

Ohio State, at 6-1, has the #40 SOS. They are ranked 3rd.
Clemson, at 7-0, has the #24 SOS. They are ranked 4th.

The gap between Clemson and OSU is 4.76, almost as much as the difference between Alabama (8-0, #11 SOS) and OSU.

West Virginia, at 6-0 vs the #28 SOS, is 15th. This is right behind 6-0 Baylor, at #114 in SOS.

I mean... damn. That's not confusing. I get that scores play a part, but how badly would Baylor need to be beating up on the tiny kids of CFB to be ahead of WVU's #28 SOS?

Does Sagarin use the old bcs formula? Or is it straight up computer?
Ok, i saw the site. I think it has to do with the golden mean, which favors teams that win by a larger margin. Clemson wins, but they haven't exactly been dominating as much tOSU. Only a computer would rank tOSU over Clemson after that Penn State loss. The computer also has no memory of Watson lighting up Bama's defense.

The red column is the old BCS formula, that I do know

Good points.

One thing I would add is that Sagarin's rankings -- at least the "predictor" ones -- have a lot more weights than simple sis. Even considering SOS, there seems be more credit given for going 2-1 against Top20-ish foes even if there are also more cupcakes on that schedule than undefeated against almost all middle of the road opponents even if the raw SOS of the latter may rank higher.

Decent logic in the sense that it's often tougher to be 8-1 when you play 3 legit teams even if the rest are weak than undefeated against all decent but not great teams.
