Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 8 + ( 0 × 0.5 ) ) ÷ 10 = 80.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
10.0%
15.0%
38.5%
75.0%
72.7%
16.7%
35.7%
85.0%
66.7%
27.3% ) = 0.443
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.621
0.536
0.450
0.554
0.555

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.800 ) + ( 40% × 0.443 + ( 20% × 0.512 ) = 0.600
( 0.320 ) + ( 0.177 ) + ( 0.102 ) = 0.600
