Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 5 = 40.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
86.7%
28.6%
33.3%
46.7%
15.4% ) = 0.421
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.466
0.552
0.459
0.506
0.526 ) = 0.502
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.400 ) + ( 40% × 0.421 + ( 20% × 0.502 ) = 0.429
( 0.160 ) + ( 0.168 ) + ( 0.100 ) = 0.429
