RPI Rankings
The Rating Percentage Index, commonly known as the RPI, is a quantity used to rank sports teams based upon a team's wins and losses and its strength of schedule. In its current formulation, the index comprises a team's winning percentage (25%), its opponents' winning percentage (50%), and the winning percentage of those opponent's opponents (25%). Strength of Schedule essentially accounts for 75% of the RPI calculation. A road win counts as 1.3 and a home win counts as 0.7, and similar for losses 1.3 for home loss, 0.7 for road loss. - Wikipedia
