Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 4 + ( 0 × 0.5 ) ) ÷ 5 = 80.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
71.4%
0.0%
28.6%
40.0%
50.0% ) = 0.380
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.443
0.800
0.590
0.663
0.575 ) = 0.614
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.800 ) + ( 40% × 0.380 + ( 20% × 0.614 ) = 0.595
( 0.320 ) + ( 0.152 ) + ( 0.123 ) = 0.595
