The Combined Average Finish is the average of a player's positions for
each track, using the merged set of all individual systems/Hertz.
Since a player can play multiple systems/Hertz, only 1 score per track is used--the
best score. The best AF possible is 1.0000,
since an average of 1 means that a player is on average 1st for everything, i.e.
32 WRs.
AF scores reward consistency--a single weak score
can negatively affect you in a big way! Your AF improves when you beat someone's scores.
It worsens when someone beats your scores. This means that your AF score can fluctuate
every week.
You need 32/32 scores to be shown. By
default, the top 100 players are shown.
