Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 5 = 60.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
33.3%
60.0%
0.0%
55.0%

0.0%
50.0%
30.0% ) = 0.331
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.472
0.531
0.433
0.516
0.591
0.577
0.438
0.524 ) = 0.521
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.600 ) + ( 40% × 0.331 + ( 20% × 0.521 ) = 0.477
( 0.240 ) + ( 0.132 ) + ( 0.104 ) = 0.477
