Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 6 + ( 1 × 0.5 ) ) ÷ 13 = 50.0%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.375 + ( 20% × 0.481 ) = 0.446
( 0.200 ) + ( 0.150 ) + ( 0.096 ) = 0.446
