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(
50.0%
60.0%
0.0%
50.0% ) = 0.400
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.539
0.236
0.721
0.675 ) = 0.543
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.750 ) + ( 40% × 0.400 + ( 20% × 0.543 ) = 0.569
( 0.300 ) + ( 0.160 ) + ( 0.109 ) = 0.569
