As mentioned in a previous post we are updating our indexing based upon Golf Australia recommended practice using the last year of data on scores from MiClub. The methodology used was to break down the scores into handicap categories (0-6, 7-12 and 13-18 for men; 0-9, 10-18, 19-27 and 28-36 for ladies) and rank the difficulty of the holes within each category.
With the men for instance, the ranking for the low 0-6 markers was then used to determine the holes ranked 1-6; the ranking for the 7-12 handicap group is then used to establish the indexes for the holes ranked 7-12 and the ranking for the 13-18 handicap group is used to establish indexes 13-18. A similar procedure was used to determine the ladies indexing.
Please see the attached file for a summary of the changes to the indexes.
