Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 14 + ( 0 × 0.5 ) ) ÷ 15 = 93.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.546
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.575
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.933 ) + ( 40% × 0.546 + ( 20% × 0.575 ) = 0.707
( 0.373 ) + ( 0.218 ) + ( 0.115 ) = 0.707
