Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 7 = 57.1%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
36.4%
30.0%
0.0%
45.5%
50.0%
60.0%
50.0% ) = 0.388
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.479
0.616
0.613
0.342
0.577
0.512
0.594 ) = 0.533
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.571 ) + ( 40% × 0.388 + ( 20% × 0.533 ) = 0.490
( 0.228 ) + ( 0.155 ) + ( 0.107 ) = 0.490
