Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 4 = 25.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
80.0%
14.3%
53.3%
18.2% ) = 0.398
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.465
0.536
0.562
0.501 ) = 0.516
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.250 ) + ( 40% × 0.398 + ( 20% × 0.516 ) = 0.362
( 0.100 ) + ( 0.159 ) + ( 0.103 ) = 0.362
