Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 0 + ( 0 × 0.5 ) ) ÷ 5 = 0.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
57.1%
100.0%
45.8%
20.0%
43.8% ) = 0.597
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.372
0.406
0.478
0.510
0.473 ) = 0.442
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.000 ) + ( 40% × 0.597 + ( 20% × 0.442 ) = 0.327
( 0.000 ) + ( 0.239 ) + ( 0.088 ) = 0.327
