Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 0 + ( 0 × 0.5 ) ) ÷ 4 = 0.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
83.3%
50.0%
55.6%
54.5% ) = 0.575
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.458
0.556
0.400
0.325 ) = 0.435
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.000 ) + ( 40% × 0.575 + ( 20% × 0.435 ) = 0.317
( 0.000 ) + ( 0.230 ) + ( 0.087 ) = 0.317
