  • Please explain the RPI to me

    Latest RPI

    What is the purpose of the RPI? Is it supposed to be a ranking of the strongest teams? Or is it supposed to show something else?

    How does Utah lose and move up from 27 to 22? Do they get points for losing to "major" schools?
    Give 'em Hell, Cougars!!!

    For all this His anger is not turned away, but His hand is stretched out still.

    Not long ago an obituary appeared in the Salt Lake Tribune that said the recently departed had "died doing what he enjoyed most—watching BYU lose."

      RPI is a formula based ranking system. The goal of RPI is to rank the strongest teams top to bottom, similar to a BCS football computer ranking system. RPI is a simple formula. It's generally too heavy on SOS compared to good computer models.

        The basic formula is 25% team winning percentage (WP), 50% opponents' average winning percentage (OWP), and 25% opponents' opponents' average winning percentage (OOWP).
        For the 2004-05 season, the formula was changed to give more weight to road wins vs home wins. A team's win total for RPI purposes is 1.4 * road wins + neutral site wins + 0.6 * home wins. A team's losses is calculated as 0.6 * road losses + neutral site losses + 1.4 * home losses.

        For example, a team that is 4-0 at home and 2-7 on the road has a RPI record of 5.2 wins (1.4 * 2 + 0.6 * 4) and 4.2 losses (0.6 * 7). That means that even though it is 6-7, for RPI purposes, it is above .500 (5.2-4.2).

        This "weighted" record is only used for the 25% of the formula that is each team's winning percentage. The regular team records are used to calculate OWP and OOWP.

        As always, only games against Division I opponents count in the RPI.

          The RPI is HUGELY important for schools in the large conferences as the Selection process really looks at it...when you get to conferences like the MAC and the MoWest, they often talk it away, etc and the fluctuation between their RPI and the schools actual seeding in the tourney is wildly different for the smaller conferences than it is for the larger conferences.

          IndyCoug put together spreadsheets of the differences and it was pretty interesting.

            Have you ever imagined UOhio nekkid, save covered with those "pretty interesting" spreadsheets? That is all they were good for!

            I'm choosing to mostly ignore your fatuity here and instead overwhelm you with so much data that you'll maybe, just maybe, realize that you have reams to read on this subject before you can contribute meaningfully to any conversation on this topic.

              Imagined it? UOhio has sent me enough of those frakkin' pictures by email...I finally had to take out a Cyber-court order that he could no longer send me emails or be faced with jail time. That stopped it for now. But he still serenades me with his boom box late at night, outside my home window, when he is in town.
