Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 7 = 28.6%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.401
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.458
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.286 ) + ( 40% × 0.401 + ( 20% × 0.458 ) = 0.366
( 0.114 ) + ( 0.160 ) + ( 0.092 ) = 0.366
