Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 6 + ( 0 × 0.5 ) ) ÷ 11 = 54.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.513
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.494
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.545 ) + ( 40% × 0.513 + ( 20% × 0.494 ) = 0.522
( 0.218 ) + ( 0.205 ) + ( 0.099 ) = 0.522
