The steps for calculating a Broken Joe GOLF Handicap are:

1. Convert gross scores to Adjusted Gross Scores

2. Calculate Handicap Differential for each score

3. Select lowest Handicap Differentials

4. Average lowest Handicap Differentials

5. Multiply the average Handicap Differential by 96%

6. Arrive at Handicap Index by truncating - deleting - the number(s) to the right of tenths

7. Calculate Course Handicap

Step 1: Convert Original Gross Scores to Adjusted Gross Scores

To arrive at an Adjusted Gross Score, you use the Broken Joe GOLF's Equitable Stroke Control (BJG ESC). BJG ESC is used to downwardly adjust individual hole scores for handicapping purposes in order to create handicaps that better represent a golfer's playing ability. BJG ESC imposes a maximum number of strokes that can be entered for any given hole. This maximum is based on the golfer's Course Handicap and is obtained from the table shown below.

Handicap Maximum Strokes

9 or less 4 on a Par 3, 5 on a Par 4 and 6 on a Par 5 (Bogey)

10 through 19 5 on a Par 3, 6 on a Par 4 and 7 on a Par 5 (Double Bogey)

20 through 29 6 on a Par 3, 7 on a Par 4 and 8 on a Par 5 (Triple Bogey)

30 through 36 7 on a Par 3, 8 on a Par 4 and 9 on a Par 5 (Quadruple Bogey)

An example of a downward adjustment may be helpful. Let's say that a player with a Course Handicap of 18 scores a nine on a Par 5 hole. His nine would be downwardly adjusted to a seven because players with handicaps in the 10 to 19 range are allowed a maximum score of seven on a Par 5 hole. Once you make adjustments, if necessary, to all eighteen holes, the sum of these 18 holes is the Adjusted Gross Score.

Step 2: Calculate Handicap Differentials for Each Score

The second step in computing a Handicap Index is to compute a Handicap Differential for each score that is to be considered in the Handicap Index calculation. The Handicap Differential is computed using the following formula:

Handicap Differential = (Adjusted Gross Score - Course Rating) X 113 ÷ Slope Rating

(The Course Rating is what the USGA deems a scratch golfer would score on a course under normal playing conditions. A Slope Rating of 113 is for a course of standard difficulty according to the USGA.)

Round the Handicap Differential to the nearest tenth (i.e., 17.25=17.3, 11.34=11.3, etc.).

Step 3: Select Best, or Lowest, Handicap Differentials

The third step in calculating your Handicap Index is to select the lowest Handicap Differentials. The following table is used when selecting the best, or lowest, Handicap Differentials. If more than 20 scores have been entered, the 10 best differentials of the 20 most recent scores are used for the calculation.

Number of Handicap Differentials Available Differentials Used

5 Lowest Adjusted Score

7 Lowest 2 Adjusted Scores

10 Lowest 3 Adjusted Scores

12 Lowest 4 Adjusted Scores

14 Lowest 5 Adjusted Scores

16 Lowest 6 Adjusted Scores

17 Lowest 7 Adjusted Scores

18 Lowest 8 Adjusted Scores

19 Lowest 9 Adjusted Scores

20 Lowest 10 Adjusted Scores

The Broken Joe GOLF does not calculate a handicap until five scores have been recorded so we will be using your lowest 5 scores from 2016 to start the season.

Step 4: Calculate the Average of the Lowest Handicap Differentials

If there are 10 Handicap scores available, calculate the average for the lowest, or best, 3 Handicap sores. If there are 16 Handicap scores available, calculate the average for the lowest, or best, 6 Handicap Differentials. Once a player has at least 20 scores, always use the 10 best, or lowest, Handicap Differentials from the most recent 20 scores.

Step 5: Multiply Average of Handicap Differentials by 0.96 or 96%

The fifth step in calculating the Handicap Index is to compute the net Handicap Differential average. For the USGA the percentage by which the Handicap Differential averages are multiplied is 96%.

Step 6: Truncate, or Delete, Numbers to the Right of Tenths

Step six in computing the Handicap Index, is to delete the digits after the tenths for the number derived in Step 5. Do round off to the nearest tenths place. As established by Broken Joe GOLF, the default maximum Handicap Index on an 18-hole course is 36 for males and 40 for females. On a nine-hole course the default maximum Handicap Index is 18 for males and 20 for females.

Example of a Handicap Index Calculation

The following is an example of how the Handicap Index is calculated using the Broken Joe GOLF System. This example assumes only 14 scores have been posted for this golfer.

Sum of the lowest five Handicap Differentials: 68.7

Average of lowest Handicap Differentials (68.7 divided by 5): 13.74

Handicap Differential Average multiplied by 96%: 13.1904

Round out digits after tenths place: 13.1

Handicap Index: 13

Step 7: Calculate Course Handicap

The final step is to calculate a Course Handicap. A Course Handicap is the number of strokes a player receives on each particular course. Determine a course handicap by multiplying the Handicap Index by the Slope Rating (from the course and tee you choose) and dividing by 113 (standard difficulty rating). Round the result to the nearest whole number.

Course Handicap = Index x (Slope Rating of Tee on Course / 113)

Example of a Course Handicap Calculation

The following assumes an index of 12.5 and a Home course slope of 120.

Course Handicap

= 12.5 x 120 / 113

= 1500 / 113

= 13.27

= 13

For 9-hole handicaps, you can follow this formula replacing the 18-hole Course Rating with a 9-hole Course Rating. The Slope is the same for 18 and 9 hole calculations.

Broken Joe Golf EXAMPLE:

I took the 5 best actual scores from 2016. While they are not truly “adjusted” they are probably close enough to get a handicap to start the 2017 season. This is the formula that we will use to track handicaps. The only thing that I need to do it put in the adjusted score, the course rating and the slope, the computer will do the rest.

In 2015, I tried to make handicaps even / fair. In 2016, I tried to make handicaps fair and not allow sand bagging plus we capped the max handicap at 36.

What I have learned is that individual handicaps are based your potential and no one can adjust for that. In fact, the 3 years (2012 – 2014) that handicaps were based on your lowest score of the year were probably the closest to actual handicaps.

Starting handicaps for 2017:

Dave - 13

Jake - 21

Joe - 22

Chris - 23

Dan - 26

Rock - 27

Leon - 28

Matt - 36

Any one thinking about being a member of Broken Joe GOLF will need to have played 5 rounds with score cards turned in to me no later than May 19th 2017
