Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 7 = 57.1%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
18.2%
80.0%
16.7%
58.3%
66.7%
63.6%
57.1% ) = 0.508
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.618
0.514
0.505
0.467
0.600
0.580
0.508 ) = 0.542
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.571 ) + ( 40% × 0.508 + ( 20% × 0.542 ) = 0.540
( 0.228 ) + ( 0.203 ) + ( 0.108 ) = 0.540
