RPI drives me crazy

  • This is how little sense the RPI makes. We beat the team that was number 11 in the RPI at their field, and we remain at number 9 in the RPI. The Tarholes beat the team at number 63 in the RPI at home, and stay ahead of us at number 8. Yet, when we play Ga this weekend, with the number 41 RPI, I bet we drop even if we sweep them. I can't figure it out, but it sure seems flawed towards the ACC. How could you otherwise explain how a sorry team like Miami is at 16, and the Taters are at 24.

    Thankfully RPI is not all they consider...that RPI is a joke. If the season ending today we would be a top 8 National seed.

  • This is one of the many explanations for RPI simplified some...it still confuses me though.

    how the committee selects hosts and national seeds. First of all, you have to do well in your conference. The committee will not give a national seed to the fourth place team in any conference. Secondly, you have to have a good RPI. RPI is based on the following four criteria (I'm over-simplifying here): 1) Division I winning percentage (25%) 2) Opponents' winning percentage (50%) 3) Opponents' Opponents' winning percentage (25%) 4) Bonus points for quality road victories against RPI top 50 opponents and penalties for bad home losses to teams outside the top 75 RPI. Lastly, the committee uses subsets of the RPI to make their decisions. They look at record against Top-25 and Top-50 RPI opponents and other data concerning subsets as well.

    in calculating RPI you do not use victories against said opponent if I remember correctly.

  • Based upon KNC's explanation, I wonder if our mid-week losses are hurting our RPI?

    Like the home loss to Wofford, or were we to lose tonight to Furman at home I would say yes,as both have winning % less than .500 for the season.Exactly how much ? I was never real good at math.....but I could figure it out, just might take awhile.Remember the RPI changes not only by your opponents win % but by their opponents win % as well. Therein starts the doubletalk called "RPI".

    Thanks for the explanation KHC. It does seem our midweek home losses have hurt us. It is counterintuitive, however, for them not to consider the victories you have against the actual opponent, but that is the NCAA for you. I guess it also goes to show that the ACC teams have figured our how to schedule cream puffs in the early season that will have good records in whatever league they play in, thus giving them a higher RPI.

    Aaron Fitt has us projected as the #7 national seed in his latest projections.

  • Here is criteria on how the RPI is calculated:

    Factor 1. Division I Winning Percentage -- 25 percent of the RPI

    Factor 2. Opponent Strength of Schedule -- 50 percent of the RPI

    Factor 3. Opponents’ Opponent Strength of Schedule -- 25 percent of the RPI

    The flaw in the RPI is the SOS component and how they determine it.

  • Glad I could help dc...the NCAA starting last year seemed to put less weight on the RPI and giving bonus points for quality road wins. LSU was a great example of this even with a 36-20 record. They had an RPI of 21 that would in most years gone by would have assured them a lock to the postseason and they trended up at the end of the season going 7-3 over their last 10 games.But 23 of their games came against teams that had a win % of .500 or less and being swept by Vandy,UF, and Arky plus losing 3 other SEC series did them in. That erased their sweep of Cal State Fullerton early in the season.

  • One of the keys to RPI is the team's Strength of Schedule (SOS).

  • The RPI is just a formula. No one is sitting at a desk considering the respective games on a given day and rating them. It's just numbers being calculated and the results are spit out.

    So I don't like the RPI or any computer ranking particularly but it doesn't make sense to compare day by day results and moves in the poll.

    The computer doesn't care if USC had a win over a tougher opponent than UNC did on a given day. It is just going to calculate based on the data it has available.

    And obviously it isn't solely based on a comparison of two teams results in a given day.

  • I also don't know that the formula cares whether USC wins or loses to wofford per se.

    Throwing aside bonuses for the moment I think everything is based on winning percentage and the two SOS factors.

    It may be that going 1-1 against wofford and say western carolina might produce the same rating regardless of how it turned out. The idea is that a significant number of games will as a whole result in a meaningful rating.

    Like I said I do not care for it or see how it is any more valid than a poll beyond it's sheer objectivity in calculation. However, it being a calculation does not mean that it's formulas are not flawed.

    I think the whole thing is somewhat silly and overblown. You won't get a definite answer no matter what you do... This seems an exercise in ceding judgment to avoid the burden of responsibility for seeding.

    But there isn't any solution to it. Take away the formulas and people blame the polls for being biased. People just don't like ratings at all.
