Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 8 = 25.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
40.0%
66.7%
44.4%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.397
0.550

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.250 ) + ( 40% × 0.609 + ( 20% × 0.491 ) = 0.442
( 0.100 ) + ( 0.244 ) + ( 0.098 ) = 0.442
