Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 5 = 40.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
35.7%
75.0%
72.7%
53.3%
40.0% ) = 0.553
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.470
0.428
0.549
0.484
0.559 ) = 0.498
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.400 ) + ( 40% × 0.553 + ( 20% × 0.498 ) = 0.481
( 0.160 ) + ( 0.221 ) + ( 0.100 ) = 0.481
