Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 1 × 0.5 ) ) ÷ 6 = 75.0%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.750 ) + ( 40% × 0.500 + ( 20% × 0.491 ) = 0.598
( 0.300 ) + ( 0.200 ) + ( 0.098 ) = 0.598
