Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.591
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.406
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.591 + ( 20% × 0.406 ) = 0.375
( 0.057 ) + ( 0.236 ) + ( 0.081 ) = 0.375
