CURRENT ACTUAL RPI RATINGS FOR GAMES THROUGH OCTOBER 30

Use the following link for access to an Excel workbook with actual RPI ratings and ranks and other data for teams based on games through October 30, 2022: RPI Report 10.30.22. On the left of the RPI Report sheet, there are five color coded columns.  These columns are based on the seasons from 2007 to the present (excluding the 2020 Covid-constrained season).  They show the rank ranges as of this stage of the season from which #1 through #4 seeds have come.  They also show the at large bubble range and that teams ranked #28 or better as of this stage of the season always have gotten at large selections.

I have included some new columns this week:

1.  In Column J I added team ranks as contributors to their opponents’ strengths of schedule.  This is right next to Column I, which is team RPI ranks.  I have put these columns next to each other to highlight a major problem with the RPI formula:  A team’s RPI rank can be very different than its strength of schedule contributor rank.

2.  In Column L I added team Balanced  RPI Ranks.  These are ranks from a variation of the RPI formula I developed.  The variation (1) effectively eliminates the discrepancy between team RPI ranks and their strength of schedule contributor ranks and (2) makes other revisions so that conferences’ teams, in non-conference games, and geographic regions’ teams, in out-of-region games, perform in accord with their ratings.  This latter change effectively eliminates the RPI’s discrimination against teams from stronger conferences and regions.

To give a sense of the seriousness of the problems that the Balanced RPI corrects, here are the pertinent columns from the linked workbook:
