Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 3 = 100.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
42.9%
0.0%
75.0%
33.3% ) = 0.393
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.530
0.900
0.500
0.306 ) = 0.643
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 1.000 ) + ( 40% × 0.393 + ( 20% × 0.643 ) = 0.686
( 0.400 ) + ( 0.157 ) + ( 0.129 ) = 0.686
