Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 6 = 33.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
27.3%
22.2%
33.3%
46.7%
42.3%
16.7% ) = 0.314
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.353
0.443
0.459
0.506
0.424
0.386 ) = 0.429
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.333 ) + ( 40% × 0.314 + ( 20% × 0.429 ) = 0.345
( 0.133 ) + ( 0.126 ) + ( 0.086 ) = 0.345
