Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 4 = 25.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

62.5%
12.5%

93.8% ) = 0.446
SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.306
0.548

0.481

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.250 ) + ( 40% × 0.446 + ( 20% × 0.429 ) = 0.364
( 0.100 ) + ( 0.178 ) + ( 0.086 ) = 0.364
