Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 1 + ( 1 × 0.5 ) ) ÷ 7 = 21.4%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
41.7%
69.2%
12.5%
45.5%
35.7%
22.2%
15.0% ) = 0.345
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.365
0.470
0.487
0.442
0.478
0.622
0.536 ) = 0.486
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.214 ) + ( 40% × 0.345 + ( 20% × 0.486 ) = 0.321
( 0.086 ) + ( 0.138 ) + ( 0.097 ) = 0.321
