Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 8 = 25.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
86.7%
16.7%
45.5%
40.0%
7.1%
54.5%
35.7%
28.6% ) = 0.394
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.466
0.598
0.442
0.492
0.427
0.434
0.548
0.552 ) = 0.495
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.250 ) + ( 40% × 0.394 + ( 20% × 0.495 ) = 0.357
( 0.100 ) + ( 0.158 ) + ( 0.099 ) = 0.357
