Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 2 + ( 0 × 0.5 ) ) ÷ 8 = 25.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
81.8%
80.0%
57.1%
70.0%
72.7%
12.5%
70.0%
14.3% ) = 0.560
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.541
0.365
0.441
0.445
0.496
0.361
0.517
0.528 ) = 0.454
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.250 ) + ( 40% × 0.560 + ( 20% × 0.454 ) = 0.429
( 0.100 ) + ( 0.224 ) + ( 0.091 ) = 0.429
