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(
70.0%
53.8%
63.6%
83.3%
57.1%
90.0%
90.0% ) = 0.670
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.593
0.505
0.351
0.399
0.354
0.519
0.588 ) = 0.454
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.670 + ( 20% × 0.454 ) = 0.426
( 0.057 ) + ( 0.268 ) + ( 0.091 ) = 0.426
