Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 3 = 33.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
50.0%
100.0%
20.0%
42.9% ) = 0.567
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.539
0.208
0.547
0.530 ) = 0.431
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.333 ) + ( 40% × 0.567 + ( 20% × 0.431 ) = 0.446
( 0.133 ) + ( 0.227 ) + ( 0.086 ) = 0.446
