Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
30.0%
28.6%
50.0%
45.5%
12.5%
60.0%
80.0% ) = 0.421
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.417
0.363
0.393
0.489
0.506
0.588
0.638 ) = 0.459
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.421 + ( 20% × 0.459 ) = 0.327
( 0.057 ) + ( 0.168 ) + ( 0.092 ) = 0.327
