Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 5 = 20.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
75.0%
90.0%
0.0%
40.0%
50.0%
0.0% ) = 0.510
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.453
0.492
0.500
0.477
0.499
0.606 ) = 0.484
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.200 ) + ( 40% × 0.510 + ( 20% × 0.484 ) = 0.381
( 0.080 ) + ( 0.204 ) + ( 0.097 ) = 0.381
