Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 7 = 28.6%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
28.6%
16.7%
73.1%
72.7%
58.3%
40.9%
70.0% ) = 0.515
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.426
0.561
0.494
0.509
0.399
0.506
0.488 ) = 0.483
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.286 ) + ( 40% × 0.515 + ( 20% × 0.483 ) = 0.417
( 0.114 ) + ( 0.206 ) + ( 0.097 ) = 0.417
