Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 8 = 12.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
55.6%
50.0%
81.8%
54.5%
30.0%
66.7%
14.3%
58.3% ) = 0.501
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.400
0.197
0.353
0.325
0.533
0.543
0.508
0.467 ) = 0.416
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.125 ) + ( 40% × 0.501 + ( 20% × 0.416 ) = 0.334
( 0.050 ) + ( 0.200 ) + ( 0.083 ) = 0.334
