Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
14.3%
50.0%
75.0%
50.0%
63.6%
12.5%
54.5% ) = 0.508
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.512
0.504
0.433
0.197
0.387
0.501
0.325 ) = 0.404
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.508 + ( 20% × 0.404 ) = 0.284
( 0.057 ) + ( 0.203 ) + ( 0.081 ) = 0.284
