Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 8 = 12.5%

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.125 ) + ( 40% × 0.583 + ( 20% × 0.452 ) = 0.374
( 0.050 ) + ( 0.233 ) + ( 0.090 ) = 0.374
