Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 5 + ( 0 × 0.5 ) ) ÷ 9 = 55.6%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
30.0%
75.0%
95.0%

25.0% ) = 0.558
SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.560
0.434
0.429
0.402

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.556 ) + ( 40% × 0.558 + ( 20% × 0.505 ) = 0.547
( 0.222 ) + ( 0.223 ) + ( 0.101 ) = 0.547
