The Rating Percentage Index (RPI) has been used by the NCAA men's basketball committee since 1981 and officially by the women's basketball committee since 1984 as supplemental data to help select at-large teams and seed all teams for the men's and women's NCAA basketball tournaments. The NCAA did not make the RPI available to member institutions in-season until the 2005-06 season, when it began doing so on a weekly basis in a bare-bones fashion. Before then, the data were kept confidential within the committees.

The three component factors which make up the RPI are as follows:

Factor I is the team's winning percentage and is 25 percent of the RPI.

Factor II is the team's opponents' winning percentage, or the team's schedule strength, excluding results against the team in question. It is 50 percent of the RPI.

Factor III is the team's opponents' opponents' winning percentage, or the team's opponents' strength of schedule, excluding results against the team in question. Factor III is 25 percent of the RPI.

So for softball all the Ratings Percentage Index (RPI) does is measure the strength of your team's schedule and compare it to the strength of your opponents.
