Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 7 + ( 1 × 0.5 ) ) ÷ 13 = 58.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.630
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.544
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.583 ) + ( 40% × 0.630 + ( 20% × 0.544 ) = 0.594
( 0.233 ) + ( 0.252 ) + ( 0.109 ) = 0.594
