Here are my RPI rankings through Week 4. Just a reminder, I've tweaked my rankings a little bit from last year. This year's format is a 30/40/30 ratio for winning percentage/opponent's winning percentage/opponent's opponent's winning percentage to mirror what Idaho is using in their RPI for 2A this year. Also I have additional modifiers for road wins, and tough road wins (road win over an opponent with a 0.666 winning percentage or better).
As a reminder the RPI gets better as the season goes along, and there are more results calculates in the spreadsheet. I hope this creates a little discussion, and feel free to send questions my way.
