Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
90.9%
76.9%
63.6%
58.8%
30.0%
100.0%
80.0% ) = 0.702
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.487
0.357
0.408
0.469
0.307
0.408
0.467 ) = 0.415
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.702 + ( 20% × 0.415 ) = 0.421
( 0.057 ) + ( 0.281 ) + ( 0.083 ) = 0.421
