Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 6 + ( 0 × 0.5 ) ) ÷ 7 = 85.7%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(

30.0%
77.8%

55.6%
55.0% ) = 0.660
SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.570
0.666

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.857 ) + ( 40% × 0.660 + ( 20% × 0.578 ) = 0.722
( 0.343 ) + ( 0.264 ) + ( 0.116 ) = 0.722
