Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 5 = 20.0%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.200 ) + ( 40% × 0.600 + ( 20% × 0.427 ) = 0.405
( 0.080 ) + ( 0.240 ) + ( 0.085 ) = 0.405
