Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 9 = 11.1%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.111 ) + ( 40% × 0.511 + ( 20% × 0.496 ) = 0.354
( 0.044 ) + ( 0.204 ) + ( 0.099 ) = 0.354
