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(
81.8%
42.9%
16.7%
83.3%
83.3%
66.7%
30.0% ) = 0.648
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.353
0.527
0.505
0.401
0.458
0.543
0.533 ) = 0.449
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.648 + ( 20% × 0.449 ) = 0.349
( 0.057 ) + ( 0.259 ) + ( 0.090 ) = 0.349
