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(
40.0%
28.6%
50.0% ) = 0.395
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.663
0.590
0.834 ) = 0.696
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 1.000 ) + ( 40% × 0.395 + ( 20% × 0.696 ) = 0.697
( 0.400 ) + ( 0.158 ) + ( 0.139 ) = 0.697
