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%

AVERAGE(
14.3%
66.7%
75.0%
63.6%
83.3%
66.7%
58.3% ) = 0.527
SOS2 represents the average of opponents' SOS1.
AVERAGE(
0.648
0.466
0.433
0.464
0.317
0.543

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.429 ) + ( 40% × 0.527 + ( 20% × 0.466 ) = 0.544
( 0.172 ) + ( 0.211 ) + ( 0.093 ) = 0.544
