For yesterday's game, kenpom predicted us to lose by one. Since we won by one, does that system just take into account that it was off by two points, or does the fact that we won count for something more?
For instance, if we were predicted to win by 3, and we instead won by 5, would it be adjusted the same amount?
It's already been answered but I'll throw in some more detail.
Kenpom predictions (the final scores) and forecast (percentage that team x wins) have to be looked at separately and as a whole. So Kenpom's prediction yesterday was a 71-70 ISU win iirc. He forecast ISU to win 51 percent of the time.
A prediction is a statement about a future event. The forecast is the probability of that event coming true. Most people are more focused on the former than the latter, which is how Kenpom judges the veracity of his statistics.
He really doesn't care about the point spreads posted, but if he shows 100 teams with a 51 percent chance of winning and 70 win he's got a problem. If 45-55 of those teams win he's right in the sweet spot, which is true on most occasions.
