Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 2 × 0.5 ) ) ÷ 6 = 50.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
90.0%
50.0%
20.0%
80.0%
0.0%
0.0% ) = 0.400
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.340
0.287
0.547
0.280
0.750
0.725 ) = 0.488
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.400 + ( 20% × 0.488 ) = 0.458
( 0.200 ) + ( 0.160 ) + ( 0.098 ) = 0.458
