Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 7 = 28.6%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
56.7%
50.0%
63.6%
36.4%
63.6%
25.0%
0.0% ) = 0.422
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.353
0.594
0.395
0.442
0.378
0.550
0.415 ) = 0.447
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.286 ) + ( 40% × 0.422 + ( 20% × 0.447 ) = 0.373
( 0.114 ) + ( 0.169 ) + ( 0.089 ) = 0.373
