And why, you might ask, is the RPI such a waste of intellectual effort? Quite simply, it violates the first law of rating systems: If we are to only consider wins and losses (which is a mistake, but politically correct), we should never penalize a team for winning, regardless of the quality of the competition. Any time a team plays they risk losing-and a meaningful rating system should reflect that. The RPI seems to believe that beating NJIT somehow makes your team less deserving, and that's a load of crap.
So, out of respect for sports of all ball shapes and sizes, I have corrected the RPI. Consistent with the philosophy of the RPI, the cRPI only considers wins and losses, opponent's winning percentage and opponent's opponent's winning percentage-but it is a much more valid reflection of reality.

So, how does the cRPI perform. First, I correlated the cRPI, the RPI and a team's winning percentage. A common, and valid complaint, against the RPI is that a team's winning percentage makes up only 25% of the equation. At r=.86, the correlation is actually quite high, but not as high as .96, the correlation between winning percentage and and a team's cRPI.
But the RPI also accounts for strength of schedule. The cRPI and RPI would use the same SOS metric, but use them in different ways. To compare the two, I have compared to two scales to the AP poll as of March 9. The cRPI rank correlates with the AP poll at r=.82 while the RPI rank correlates at only .69. My corrected RPI not only does not undervalue winning, but it is a significantly better reflection of how people judge teams.
