How Improvement Is Calculated
Improvement is based on comparing a pilot's top scores from the current season to their top scores from the prior season. You must have a minimum number of scores in each season to be included. The minimum for Unlimited TD is 6, for the Hand Lauch division it is 5.
"Current Avg." and "Prior Avg." are the average of the selected top Overall scores for the season.
Improvement is the difference in the average scores from season to season.
