Handicap 2014 update

You may notice a change in your handicap. The course updated the slope and rating (and some yardages as well). I entered the new data and the system recalculates accordingly. Below is an example of how handicap is calculated. If you would like to see your specific data let me know I can run the report for you. - Thom


1. Handicap Setup for this League is as follows...      
  Handicap Regulars: 80 Subs: 80          
  Number of scores handicap based on: 20          
  Minimum number of scores needed before a handicap can be calculated: 1    
  # of Scores Discard Discard            
  Available Highest Lowest            
  1 0 0            
  2 0 0            
  3 0 0            
  4 0 0            
  5 0 0            
  6 0 0            
  7 0 0            
  8 0 0            
  9 0 0            
  10 0 0            
  11 0 0            
  12 0 0            
  13 0 0            
  14 0 0            
  15 0 0            
  16 0 0            
  17 0 0            
  18 0 0            
  19 0 0            
  20 0 0 <<Thom has 23 scores prior to event #4  
        so the underlined parameters are used to determine  
        which scores to use for handicapping.    
                   
2. The differentials for these scores are calculated...      
      Adjusted     Course Course    
  Date Event # Grs Scr Course Played Tee Rating Slope Differential Used
  05/14/14 Evt #3 48 Prairies Front W 35.2 124 11.7 Used
  05/07/14 Evt #2 49 Prairies Back W 34.0 128 13.2 Used
  04/30/14 Evt #1 51 Prairies Front W 35.2 124 14.4 Used
  Practice Score 43     34.9 117 7.8 Used
  Practice Score 42     34.9 117 6.9 Used
  Practice Score 44     34.9 117 8.8 Used
  Practice Score 49     34.9 117 13.6 Used
  Practice Score 51     34.9 117 15.5 Used
  Practice Score 48     34.9 117 12.7 Used
  Practice Score 42     34.9 117 6.9 Used
  Practice Score 44     34.9 117 8.8 Used
  Practice Score 43     34.9 117 7.8 Used
  Practice Score 41     34.9 117 5.9 Used
  Practice Score 43     34.9 117 7.8 Used
  Practice Score 41     34.9 117 5.9 Used
  Practice Score 45     34.9 117 9.8 Used
  Practice Score 47     34.9 117 11.7 Used
  Practice Score 46     34.9 117 10.7 Used
  Practice Score 45     34.9 117 9.8 Used
  Practice Score 44     34.9 117 8.8 Used
  Practice Score 45     34.9 117 9.8  
  Practice Score 43     34.9 117 7.8  
  Practice Score 46     34.9 117 10.7  
                   
  Only the last 20 scores are considered for handicapping.          
                   
    The equation for calculating a differential is ...          
    Diff = (Adjusted Gross Score - Rating) x (113 / Slope)          
                   
3. Use the differentials to calculate a handicap.        
                   
  Differentials 'used' are added together...          
  11.7+13.2+14.4+7.8+6.9+8.8+13.6+15.5+12.7..etc.. = 198.5          
                   
  Then divide by the total number used.          
  Pre-Handicap = 198.5 / 20 Pre-Handicap = 9.925          
                   
  Thom is a regular player, so according to the          
  handicap setup the Handicap Percent is 80          
  Handicap = 9.925 x 80   Handicap = 7.94 (Digits after hundredth place are deleted)  
                   
  Convert the handicap to a 'course' handicap using the slope of the course being played. (Prairies Back)
  Handicap = Handicap x (Slope / 113)          
  Handicap = 7.94 x (128 / 113)            
  Handicap = 8.99              
                   
  Final Handicap = 8.99
