Course Analysis Methods

The scores posted to your handicap system provide valuable information with which you can analyze the play of your course and evaluate the appropriateness of its Handicap Hole Ratings.  GHM provides two analysis methods: Course Analysis and Group A/Group B Analysis.  Both methods require a History Database; if you have not maintained a History Database these analyses cannot be done.  Further, both methods are meaningful only if scores have been posted on a hole-by-hole basis; the Group A/Group B Analysis requires hole-by-hole scores.

Course Analysis
This analysis provides a statistical summary of Total Scores and, for hole-by-hole scores, a ranking of the course holes in their relationship to Par.  The Total Scores information includes the number, average, and average strokes over Par for 18-hole and 9-hole scores, and the number and percentage of 18-hole scores in 10-stroke ranges.  This screen window is used for your specification of the players and types of scores to be included in the analysis.  Note that you can base the analysis on a selected date range and/or a range of  Handicaps.

When you click the Proceed button you are presented with a Course Selection Screen (not illustrated) from which you select the Home Course to be analyzed.  The analysis then proceeds automatically.  A Processing Status Screen (not illustrated) is presented that shows the number of history records skipped for various reasons related to your specifications, and from which you can print the Course Analysis Report.

Note that the analysis can be done for individual players.  If any of your players have consistently entered scores on a hole-by-hole basis, you can provide them with an attractive season-end statistical analysis of their home course play.

Again, this analysis is meaningful only if scores have been entered on a hole-by-hole basis.  Without hole-by hole scores you will receive only a summary of total scores versus Par.



Group A / Group B Analysis
This analysis method is the one recommended by the USGA for evaluating a course's Handicap Hole Ratings.  It requires hole-by-hole scores and it is recommended that there be approximately 200 scores from each of two groups of players in different handicap ranges (the A and B Groups).  The analysis is based on the differential between the average score of each group.  The method is described in detail in Section 17.2 of the USGA Handicap System Manual.

This screen window is used for your specification of the types of scores to be included in the analysis.  Note that you can base the analysis on a selected date range and limit the number of scores used for an individual player.  When you click the Proceed button you are presented with a Course Selection Screen (not illustrated) from which you select the Home Course to be analyzed.  The analysis then proceeds automatically.  A Processing Status Screen (not illustrated) is presented that shows the number of history records skipped for various reasons related to your specifications, and from which you can print the A/B Analysis Report.

The Group A / Group B Analysis requires scores that have been entered on a hole-by-hole basis.
