Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.585
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.422
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.585 + ( 20% × 0.422 ) = 0.376
( 0.057 ) + ( 0.234 ) + ( 0.084 ) = 0.376
