Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 1 × 0.5 ) ) ÷ 10 = 15.0%
SOS1 represents the average of opponents' Win% for each game.

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.150 ) + ( 40% × 0.536 + ( 20% × 0.489 ) = 0.372
( 0.060 ) + ( 0.214 ) + ( 0.098 ) = 0.372
