Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 1 × 0.5 ) ) ÷ 7 = 21.4%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
66.7%
54.2%
33.3%
36.4%
83.3%
57.1%
75.0% ) = 0.580
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.473
0.597
0.297
0.465
0.484
0.443
0.371 ) = 0.447
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.214 ) + ( 40% × 0.580 + ( 20% × 0.447 ) = 0.407
( 0.086 ) + ( 0.232 ) + ( 0.089 ) = 0.407
