Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 7 = 57.1%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

0.0%
63.6%
30.0%
100.0%
57.1%
66.7% ) = 0.508
SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.625
0.464
0.359
0.587
0.508

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.571 ) + ( 40% × 0.508 + ( 20% × 0.492 ) = 0.530
( 0.228 ) + ( 0.203 ) + ( 0.098 ) = 0.530
