A team's win-loss record only counts for 25% of the RPI calculation. Playing non-conference games on the road is valuable because every road win counts as 1.4 wins in the calculation, while road losses only count as 0.6 losses.
Looking at OU's home and road records this year, the Sooners' home record is unblemished at 8-0, but the RPI win-loss adjustment gives us 4.8-0.0 for home games.
In road games OU is 4-5, which RPI calculates as 5.6-3.0 for road games.
The 1-2 record in the Paradise Jam calculates as exactly that for the RPI.
So OU's overall record for RPI purposes is 11.4-5.0, not the actual record of 13-7.
That's a .700 winning percentage for 20 games, the equivalent of 14-6. Now, where's that argument against scheduling road games?
Let's compare that against the two third-place teams in the conference, Iowa State and TCU. Both have played 13 home games, with records of 11-2 and 10-3 respectively. So Iowa State's calculated home record is 6.6-2.8, and TCU's is 6.0-4.2. Iowa State won their only neutral court game for 1-0, TCU split 2 for 1-1. On the road ISU is 2-4 and TCU is 2-3, those calculate as 2.8-2.4 and 2.4-1.8 for RPI purposes respectively.
So for the RPI, ISU is 10.4-6.2 and TCU is 9.8-7.0. Those RPI winning percentages are .630 for ISU and .580 for TCU. Both teams played 5 MORE home games than OU.
