Agreed and I think good systems already do this.
I could be totally wrong but with Kenpom.........so there's predicted scores before each game. Say UK plays a team ranked 175th. So average team. Let's say the predicted score has them winning by 20.
Now let's say there's another team........ranked 50th and they are predicted to win by 10.
UK ends up winning both games by 20.
The first game.......UK did what was expected........their ratings would more or less stay the same.
The second game UK did better than expected........by 10 points. Which means they did better than expected either on offense or defense (or perhaps both). As a result, their adjusted offensive or defensive efficiency would rise making their overall rating rise.
So I think good systems have this factored in already. A 30 point win over the 300th ranked team = not gonna make u rise. A 30 point win vs the 50th ranked team? Your jumping up.
Doesn't Sagarin do something similar with it's "predictor" thing? As in, the predictor thinks your are ___ points ahead of your opponent, and if you trounce that prediction the computer propels you much further ahead than if you had simply met it?
