Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 7 = 14.3%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
45.5%
57.1%
100.0%
90.0%
80.0%
33.3%
33.3% ) = 0.627
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.442
0.289
0.238
0.217
0.393
0.462

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.143 ) + ( 40% × 0.627 + ( 20% × 0.354 ) = 0.379
( 0.057 ) + ( 0.251 ) + ( 0.071 ) = 0.379
