NCAA DI SOFTBALL RPI

updated to the source either timely or correctly.

RPI is calculated by using 25 percent of the team’s winning percentage; 50 percent of its opponents’ average winning percentage; and 25 percent of its opponents’ opponents’ average winning percentage. A team with a record of 8-0, opponents’ winning percentage of .600 and opponents’ opponents’ winning percentage of .450 would have an RPI of 0.6625. That would read: (1.000 x 0.25) + (0.600 x 0.50) + (0.450 x 0.25) or 0.2500 + 0.3000 + 0.1125= 0.6625. 

Only games against other DI teams are included. Ties are also not utilized in computations.
