Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 0 + ( 1 × 0.5 ) ) ÷ 4 = 12.5%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
41.7%
90.0%
42.3%
57.1% ) = 0.578
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.365
0.217
0.424
0.433 ) = 0.360
RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.125 ) + ( 40% × 0.578 + ( 20% × 0.360 ) = 0.353
( 0.050 ) + ( 0.231 ) + ( 0.072 ) = 0.353
