Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 6 = 33.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
66.7%
33.3%
63.6%
50.0%
35.0%
16.7% ) = 0.442
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.453
0.439
0.554
0.369
0.550
0.386 ) = 0.459
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.333 ) + ( 40% × 0.442 + ( 20% × 0.459 ) = 0.402
( 0.133 ) + ( 0.177 ) + ( 0.092 ) = 0.402
