Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 11 = 36.4%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.481
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.472
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.364 ) + ( 40% × 0.481 + ( 20% × 0.472 ) = 0.432
( 0.146 ) + ( 0.192 ) + ( 0.094 ) = 0.432
