Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 10 = 40.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

SOS2 represents the average of opponents' SOS1.
AVERAGE(

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.400 ) + ( 40% × 0.531 + ( 20% × 0.462 ) = 0.438
( 0.160 ) + ( 0.212 ) + ( 0.092 ) = 0.438
