Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 9 = 44.4%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.444 ) + ( 40% × 0.446 + ( 20% × 0.471 ) = 0.450
( 0.178 ) + ( 0.178 ) + ( 0.094 ) = 0.450
