Handicap Calculation Parameters

The purpose of handicapping is to ensure equal competition among players of different abilities. League Manager provides a handicap using the 3 following methods:
Note: You can see how a player’s handicap is being calculated at any time. Just highlight the golfer in question and press F10, or click the Help menu and select “How is golfer handicapped?”. A report will appear showing exactly how the player’s handicap is being calculated. 
To view the Handicap Parameters form, from the Setup menu, choose “Handicap Calculation Parameters”.
Note: Handicap parameters can only be set while viewing event #1. The same handicap formula must be in effect for the entire season. 
To set up handicapping
Note: League Manager retrieves the rating and slope from the Course Library. The Course Rating and Course Slope values are entered for each course\tee your league plays. These values are entered in your Course Library. 
Handicap = (Adjusted Gross Score  Par) x (113 / 113)
Handicap = Adjusted Gross Score – Par
Note: The more scores a handicap is based on the less fluctuation you will see in handicaps. In other words, if a golfer’s handicap is based on 20 scores, any new score will have a 1 in 20 (5%) weight on his handicap. However, if his handicap is based on only 4 scores, any new score would have a 1 in 4 (25%) weight on his handicap. 
Example: Assume John Doe shoots a 50, the handicap percent figure is 100% and the rating and slope of the course he plays is 36.0 and 113 respectively. He comes into event one with no handicap. He has submitted no practice scores or history of scores to establish a handicap. The handicap for event one will be based on what he shoots in event one. 50  36 x 113/113 x 1.00 = 14 hcp. But what if he had shot a 40? His handicap would be 4036 x 113/113 x 1.00 = 4 hcp. The problem is, if John shoots a high score he gets a high handicap, if he shoots a low score he gets a low handicap. So no matter what he shoots he is assured of receiving the same net score. Just one score is not a good indicator of the skill of any player. Plus, with no history of scores, the handicap for event two is the same, based on what he shot in event one... there are no more prior scores to base a handicap on. In event three John’s handicap will finally be based on two scores, what he shot in event two and in event one. As you can see, for players that do not have a history of scores (practice scores), you can expect a large fluctuation in handicaps for the first few events. Solution to problem: Most league golfers have played golf before and can at least submit a few past rounds they have shot. Put these in as practice rounds to establish an initial handicap. A fair handicap will be established much more quickly with less fluctuation. Note: An instantaneous handicap will never be less than scratch (0). 
Example: If you want League Manager to calculate a handicap based on a golfer’s last 6 scores, the parameters would be filled in... “# of scores handicap based on”: 6 But when a golfer has 6 scores to base a handicap on do you want to drop any high or low scores before calculating a handicap? What if a golfer only has 5 prior scores to look at? Do you want League Manager to drop any high or low score then? What should League Manager do if a golfer has only 4, 3, 2, or 1 scores available? You must fill in the table to indicate exactly what you want the program to do in every instance it may encounter. For example you may decide on the following…
The Parameters will be filled out as follows…
According to the table above…

Note: Many leagues choose to drop some high scores, so that one bad score does not increase a handicap excessively. This helps deter sandbagging. If a golfer shoots an unusually high score, he may think it will make his handicap go up, but in reality it has no effect on his handicap since this high score will be discarded for handicap purposes. 
Example: If Handicap Percent figure = 80% and a golfer’s handicap is 12 then … Final Handicap = Handicap x 80% Final Handicap = 12 x .80 = 9.6 Final Handicap = 9.6
