Optimism: Calculations on RPI impact from Sooners and KU

[CBradSmith]

Going with basic formula: (.25*Win%) + (.5*OppWin%) + (.25*OppOppWin%) I've calculated the contribution of each of the current 3 portions of the equation and the impact of games against ou and KU on the 1st and 2nd portions of the equation....

Current RPI: 0.5519

Current

• Team Contribution (OSU)
  
  • 0.14516
• Opp Contribution (Opp Win%)
  
  • 0.22452
• Opp Opp Contribution
  • 0.18221

Beat ou

• Team Contribution (OSU)
  
  • 0.14843 (+0.00327)
• Opp Contribution (Ou's Win%)
  
  • 0.22816 (+0.00364)

Post Beat ou RPI ~ .5588 - Good to get in the 73 to 76 range.

Kansas

• Team Contribution (OSU)
  
  • Lose -0.00449
  • Win +0.0030
• Opp Contribution (KUs Win%)
  • In both cases +0.0083

Post KU RPI - In both cases our RPI rises. It rises the most simply by being able to add Kansas's W-L record into our aggregate Opponent W - L record.

Win: 0.5701 Rank about 60
Lose: 0.5626 Rank in the rang 65 to 67


These adjustments are made strictly to the 1st and 2nd portion of the RPI equation: our Win% and our Opponents Win%.

For both ou and Kansas, it is safe to assume that the 3rd part of the RPI equation will only help us, as both of their Opponents Win% are significantly higher than our own...but that adjustment is not captured in the estimates above.
