Over the years, there has been a lot of talk on various threads concerning media polls, QRF, RPI, etc. Thought it would be informative to get a thread going to get an explanation of each and which seems to be the most accurate. If someone has insight on the basic concepts of each, what are the driving factors of each, please put on here. Also, which one seems to be the best "predictor" from the start of the season to how the season ends up and which seems to be the weakest. I for one have noticed that many times they are very skewed at beginning of year and start "predicting" closer at the end of the year, which is real no help because all the games have been played so we already know the best teams. Looking for the one that "predicts" the most accurately in the early-mid portion of the year.
RPI does use: Winning % of opponent's opponents.
QRF does use: Margin of victory and SOS of opponents.
