In past years, I usually compared the RPI, Pablo, and seeding/placement of the NCAA teams to see which teams had RPI rankings that differed significantly from Pablo and who got a favorable/unfavorable seeding and/or opponent (w/ respect to Pablo rankings). Like most people on this forum, I assume that Pablo is a much better indicator of a teams strength.
I don't have access to Pablo, so I did a comparison to the Massey Rankings.
