Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 12 + ( 0 × 0.5 ) ) ÷ 16 = 75.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.567
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.527
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.750 ) + ( 40% × 0.567 + ( 20% × 0.527 ) = 0.632
( 0.300 ) + ( 0.227 ) + ( 0.105 ) = 0.632
