Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 11 = 27.3%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.273 ) + ( 40% × 0.531 + ( 20% × 0.405 ) = 0.360
( 0.109 ) + ( 0.212 ) + ( 0.081 ) = 0.360
