Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 4 = 75.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
60.0%
85.7%
50.0%
0.0% ) = 0.489
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.701
0.478
0.609
0.804 ) = 0.648
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.750 ) + ( 40% × 0.489 + ( 20% × 0.648 ) = 0.625
( 0.300 ) + ( 0.196 ) + ( 0.130 ) = 0.625
