I understand that, but your conference only accounts for around 65% of your games pre-tourney, assuming you make it to the CT.
You want us to believe that you went 25-4 with a top-50 non-con, with no losses to the crap teams in your conference, and only had a 74 RPI? Sorry, not believing that for a second. Unless (1) your entire conference went winless against their non-con, or (2) your non-con wasn't actually good and just beat up on sims, upping your SoS during non-con, then they got trashed during conference, I don't believe that you had a good non-con schedule last season.
To be 25-4 and only have a 74 RPI, you'd have to have at best a mid-100s SoS.
