Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 9 = 22.2%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.222 ) + ( 40% × 0.643 + ( 20% × 0.476 ) = 0.452
( 0.089 ) + ( 0.257 ) + ( 0.095 ) = 0.452
