FYI, RPI isn't a ranking system.

The RPI measures a team's schedule strength and how the teams fares against that schedule. It does not measure how good an individual team is, and it does an even worse job measuring how good a conference is. Statistically, playing a bad team that finishes 12-16 is four times more beneficial than a bad team that winds up 3-25. Given that margin of victory plays no role in its calculation, both scenario's tell you nothing about how good the actual team being measured is. RPI is currently still in existence mainly because it does not take into account margin of victory in its calculation, which inherently seems like the formula’s obvious flaw, but is done because the NCAA is adverse to seem as they are encouraging coaches to run up the score or influence point spreads that are associated with gambling.
"I don't encourage people to use this [the RPI] for ranking teams. If anything, I discourage it. I bend over backwards to try to explain that this is NOT designed to be a definitive ranking of teams and the selection committee does not use it that way either."
