Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 2 = 50.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
36.4%
73.3%
50.0%
25.0%
70.0%
36.4%
66.7% ) = 0.548
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.535
0.444
0.615
0.439
0.605
0.650
0.567 ) = 0.490
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.548 + ( 20% × 0.490 ) = 0.517
( 0.200 ) + ( 0.219 ) + ( 0.098 ) = 0.517
