Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 5 + ( 0 × 0.5 ) ) ÷ 10 = 50.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

83.3%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.568 + ( 20% × 0.516 ) = 0.530
( 0.200 ) + ( 0.227 ) + ( 0.103 ) = 0.530
