Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 0 × 0.5 ) ) ÷ 8 = 12.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
92.3%
27.3%
21.4%
60.0%
86.7%
25.0%
35.7%
40.9% ) = 0.487
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.543
0.353
0.345
0.473
0.466
0.567
0.548
0.381 ) = 0.460
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.125 ) + ( 40% × 0.487 + ( 20% × 0.460 ) = 0.337
( 0.050 ) + ( 0.195 ) + ( 0.092 ) = 0.337
