Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 0 + ( 0 × 0.5 ) ) ÷ 4 = 0.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
60.0%
50.0%
63.6%
37.5%
50.0% ) = 0.500
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.380
0.484
0.387
0.485
0.395 ) = 0.432
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.000 ) + ( 40% × 0.500 + ( 20% × 0.432 ) = 0.286
( 0.000 ) + ( 0.200 ) + ( 0.086 ) = 0.286
