Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 1 × 0.5 ) ) ÷ 9 = 16.7%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
76.9%
70.8%
40.0%
28.6%
60.7%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.483
0.306
0.363
0.429

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.167 ) + ( 40% × 0.444 + ( 20% × 0.455 ) = 0.344
( 0.067 ) + ( 0.178 ) + ( 0.091 ) = 0.344
