Warren Nolan is consistent with the official NCAA reporting of RPI and RPI ranking, unless there is a mistake in a game result (which both the NCAA and Warren Nolan occasionally make). Both have the Cajuns at an RPI of .63791 and an RPI ranking of 15.
It is the Adjusted RPI that the NCAA reports, but Warren Nolan does not include in their RPI report. These bonuses that represent the difference between RPI and Adjusted RPI are relatively well known and you can add them to the respective RPIs (what I call Base RPI) to determine what the Adjusted RPIs are (and Adjusted RPI rankings) before the official report is published. The only tricky RPI bonus is determination of the teams that qualify for the special Road NC SOS bonus, which the Cajuns do (.0026 bonus) ... one of twelve teams this week that do qualify. Without it, the Cajuns would have an Adjusted RPI ranking of 13.
