StatFox Driver Ratings are based on a weighted combination
of 3 factors. The first is the drivers finishing position in recent races.
The second factor is the driver's average qualifying position in recent
races. Finally, the drivers ability to finish the race (DNF index) is
factored. To calculate hypothetical race odds, determine the sum of the
ratings of all drivers participating in a race. A driver's odds of winning
are approximately equal to their rating divided by the sum of ratings
of all participants.
