Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 8 = 37.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
0.0%
70.0%
62.5%
0.0%

38.5%
35.0% ) = 0.320
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.590
0.605
0.478
0.381
0.615
0.569

0.572 ) = 0.536
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.375 ) + ( 40% × 0.320 + ( 20% × 0.536 ) = 0.385
( 0.150 ) + ( 0.128 ) + ( 0.107 ) = 0.385
