Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 3 × 0.5 ) ) ÷ 9 = 50.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
8.3%
12.5%
30.0%
85.7%
14.3%

50.0%
64.3%
83.3% ) = 0.197
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.620
0.501
0.533
0.443
0.508

0.317 ) = 0.521
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.197 + ( 20% × 0.521 ) = 0.463
( 0.200 ) + ( 0.079 ) + ( 0.104 ) = 0.463
