Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 6 = 66.7%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
22.2%
33.3%
33.3%
63.6%
53.8%

SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.554
0.408
0.667
0.557
0.477

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.667 ) + ( 40% × 0.415 + ( 20% × 0.556 ) = 0.544
( 0.267 ) + ( 0.166 ) + ( 0.111 ) = 0.544
