Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 8 = 37.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
46.2%
20.0%
64.3%
36.4%

61.5%
23.1%
70.0% ) = 0.414
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.525
0.468
0.381
0.409
0.468
0.474
0.478
0.461 ) = 0.458
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.375 ) + ( 40% × 0.414 + ( 20% × 0.458 ) = 0.407
( 0.150 ) + ( 0.166 ) + ( 0.092 ) = 0.407
