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%
50.0%
66.7%

0.0% ) = 0.485
SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.567
0.504
0.514
0.556
0.380
0.484

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.375 ) + ( 40% × 0.485 + ( 20% × 0.508 ) = 0.376
( 0.150 ) + ( 0.194 ) + ( 0.102 ) = 0.376
