Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 3 + ( 0 × 0.5 ) ) ÷ 7 = 42.9%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
45.8%
50.0%
69.2%
60.0%
0.0%
30.0%
12.5% ) = 0.482
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.478
0.296
0.490
0.418
0.499
0.578
0.436 ) = 0.460
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.429 ) + ( 40% × 0.482 + ( 20% × 0.460 ) = 0.418
( 0.172 ) + ( 0.193 ) + ( 0.092 ) = 0.418
