Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 9 = 22.2%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
40.0%
38.5%
65.0%
40.9%
54.5%

25.0%
61.5%
46.7% ) = 0.488
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.492
0.450
0.457
0.381
0.434

0.506 ) = 0.470
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.222 ) + ( 40% × 0.488 + ( 20% × 0.470 ) = 0.378
( 0.089 ) + ( 0.195 ) + ( 0.094 ) = 0.378
