Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 10 = 20.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

30.0%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.476

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.200 ) + ( 40% × 0.510 + ( 20% × 0.494 ) = 0.392
( 0.080 ) + ( 0.204 ) + ( 0.099 ) = 0.392
