Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 11 = 18.2%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.182 ) + ( 40% × 0.618 + ( 20% × 0.454 ) = 0.418
( 0.073 ) + ( 0.247 ) + ( 0.091 ) = 0.418
