Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 6 = 16.7%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
56.2%
30.0%
58.8%
64.3%
60.7%
72.7% ) = 0.566
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.489
0.307
0.469
0.382
0.400
0.496 ) = 0.409
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.167 ) + ( 40% × 0.566 + ( 20% × 0.409 ) = 0.388
( 0.067 ) + ( 0.226 ) + ( 0.082 ) = 0.388
