Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 9 = 33.3%
SOS1 represents the average of opponents' Win% for each game.

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.333 ) + ( 40% × 0.260 + ( 20% × 0.473 ) = 0.299
( 0.133 ) + ( 0.104 ) + ( 0.095 ) = 0.299
