Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 7 + ( 0 × 0.5 ) ) ÷ 10 = 70.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
) = 0.547
SOS2 represents the average of opponents' SOS1.
AVERAGE(
) = 0.546
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.700 ) + ( 40% × 0.547 + ( 20% × 0.546 ) = 0.608
( 0.280 ) + ( 0.219 ) + ( 0.109 ) = 0.608
