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(
71.4%
14.3%
66.7%
14.3%
37.5%
50.0%
60.0% ) = 0.512
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.508
0.508
0.424
0.543
0.443
0.395
0.380 ) = 0.449
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.512 + ( 20% × 0.449 ) = 0.361
( 0.057 ) + ( 0.205 ) + ( 0.090 ) = 0.361
