Handicap Professional - U.R.M. Powered Software by Sironix

Product Overview


Handicap Professional is a software program that allows golfers to estimate their own handicap index and keep track of their progress and statistics over time.

At the core of the system is a database to store the results for every round of golf that you play. Because the database includes all of your historical data, the program can calculate your handicap at any point in time, allowing you to track your progress from month to month and season to season. In addition to handicap calculation, other functions are provided to highlight your course records, as well as your scoring averages by course, by month, and by season.

The program also allows you to enter a number of statistics for each round that you play. These include, greens in regulation, total putts, putts per green in regulation and sub-par holes. Statistical correlation graphs allow you to see how these statistics affect your score. (see PGA tour example correlation data )

The program can manage data for any number of players. This allows multiple family members and friends to keep track of their progress using the same database. You can calculate handicaps for your friends and family members and avoid the customary haggling for handicap strokes on the first tee. You can use the league statistics screen to view summarized handicap and statistical data for all of the players in the database.

Unlike other products, Handicap Professional does not require you to add your data on a hole-by-hole basis. This can become very time consuming over the long term.

As you keep your score during a round of golf, you should mark the following for each hole.

  • strokes for the hole
  • a check mark to indicate a green in regulation (GIR)
  • the number of putts for the hole

These are the most important statistics for analyzing your progress and are very easy to track as you mark your score. Other measurements, such as fairways hit and sand save percentage are interesting but much less significant. Tracking too many details on your scorecard is cumbersome, impractical and can promote slow play.

When you enter your total score, you should also include the total GIR, total putts, and the total number of putts for the greens hit in regulation as well as the number of sub-par holes. From this minimal amount of data entry, the system can track the following for you by course, by season, and in total.

  • conventional handicap
  • slope adjusted handicap index
  • greens in regulation %
  • average putts per round
  • putting average per GIR
  • putting average per GNIR (greens not hit in regulation)
  • sub-par hole percentage

All of the above statistics can be plotted against each other and against your scoring average. The resulting correlation scatter graphs illustrate which statistics have the most effect on your handicap.

Greens in regulation % is a statistic that correlates well with your scoring average. At all levels of play it indicates the ability to get the job done from tee to green. For scratch players through to high handicappers, this statistic will usually closely predict your scoring average and handicap.

Average putts per round on the other hand does not correlate as well with scoring average. Scratch players will often take as many putts as the average player depending on how many greens they hit. Putting average per green in regulation is the best indicator of putting ability because it takes other variables such as GIR % and short game ability out of play.

Putts per GNIR is a very accurate indication of short game proficiency for most low and middle handicap players. It assumes that most of the time, greens not hit in regulation become save opportunities. Although this is not always the case, it provides a very good indication without having to keep track of save opportunities on a hole-by-hole basis.

An analysis of scoring statistics for PGA tour pros reveals that scoring average and money winnings have more to do with short game skill than driving accuracy or distance. The following statistical rankings and correlation values are based on thousands of rounds of PGA tournament golf. For example, there is a 73.3% correlation between putts per green in regulation and scoring average and there is a 65.1% correlation between putts per green in regulation and money earned. Driving distance correlates poorly with scoring average and money earned. This supports the old adage, drive for show, putt for dough.

Correlation % with Scoring Average / Money Earned

  1. 73.3% / 65.1% - Putts per green in regulation
  2. 63.9% / 57.9% - Putts per green not hit in regulation
  3. 57.3% / 48.2% - Greens hit in regulation
  4. 47.0% / 43.1% - Total putts
  5. 36.8% / 32.9% - Driving Distance
  6. 25.1% / 19.9% - Fairways hit in regulation
