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(
50.0%
0.0%
50.0%
25.0%
50.0%
75.0%
0.0% ) = 0.350
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.609
0.538
0.620
0.648
0.575
0.500
0.444 ) = 0.598
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.400 ) + ( 40% × 0.350 + ( 20% × 0.598 ) = 0.420
( 0.160 ) + ( 0.140 ) + ( 0.120 ) = 0.420
