NAIA SOFTBALL RPI

Results are collected daily from prestosports.org. If results below are not correct, scores may not have been uploaded 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 teams of the same division are included. For example, if an NAIA team plays against an NCAA DII or USCAA school those results are not included, nor are ties.
