I think you should re-read the footnote, dude.

Ken Pomeroy is predicting UMass will win 8 of the last 13. His game-by-game predictions add up to wins of 9 of the last 13 but that is NOT what he is predicting for the group of 13 games.

Small differences in the ratings can result in big differences in the results predicted for all games played by all teams. They may agree closely on UMass but not for every other team. I have seen detailed comparisons of the different rating systems and some perform consistently better than others. Again, small differences have big impacts when you look at all 300+ D1 teams.

Thanks for setting me straight, DUDE. Now I know how to properly apply this completely useless information.

If your only interest is whether or not you will make it into the NCAAs then the RPI is for you. If you want to get a measure on how good your team has played to date and what their chances are of beating the next team and/or by how much then the RPI is useless and irrelevant. MassMan06 seemed to be looking for the latter. As such, Greenfield, Sagarin, Massey and some others are far more relevant.
So you are sayng that the other power rating are good at predicting the chances of my team winning a game?

Did these rating help you predicate the UCONN and the GW games? How relevent were they on these games? Or maybe they told you FSU would beat Wake Forest.
All rating are just opinions or stats. We all know opinions vary and stats lie.
Except for the end of the year when they can help a team get in a tournement all rating are just for giving basketball junkies something to aruge about. :wink:

But thank you D.S. for maintaining this thread. I find it interesting.

The ratings only lead to a statistical prediction for the next game. It is all about probabilities. The team with the higher rating has a greater than 50% probability of winning but it isn't 100% nor is it ever claimed to be. If it were that simple we wouldn't have to play the games. The bigger the difference in ratings, the higher the probability is that the higher rated team will win. You would probably be surprised at how high the probability was of UMass beating either UConn or GW based on the ratings.
