Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 7 + ( 1 × 0.5 ) ) ÷ 14 = 53.6%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.382
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.506
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.536 ) + ( 40% × 0.382 + ( 20% × 0.506 ) = 0.468
( 0.214 ) + ( 0.153 ) + ( 0.101 ) = 0.468
