[wiper]

can someone explain how the weekly nfl sagarin ratings work? specifically, every friday i get the usa today, and read through the page where they have his ratings, and rundowns of all the games...every week you add a certain amount for the hometeam (this week it's 1.71), and then you get your matchup.

how does he come to the 1.71? last week it was 2.95 i'm pretty sure..

is that just an average of what each hometeam's advantage is? and how can you assign the same amount of points to every home team??
