Week 9 Elo movers so far: Jaguars up 17, Ravens down 17

Jacksonville Jaguars rose to 1622; Baltimore Ravens fell to 1486.

Elo moves after every game: the winner takes points from the loser, more for an upset and more for a big margin, scaled by K = 20. A swing of 17 is a large one-week move; typical is 10 to 20.

Ratings feed next week's numbers directly, so these moves are already in the Predictions page. Elo alone trails the market over the long run, which is why The System weights it a quarter, but it is the part of the forecast that explains itself.
