Handicap Calculation

1. Handicap Setup for this League is as follows...      
  Handicap Regulars: 80 Subs: 80          
  Number of scores handicap based on: 10          
  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 <<Player has 20 scores prior to event #2  
        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
  Practice Score 43     36.0 113 7.0 Used
  Practice Score 39     35.0 113 4.0 Used
  Practice Score 46     36.0 113 10.0 Used
  Practice Score 40     35.0 113 5.0 Used
  Practice Score 42     36.0 113 6.0 Used
  Practice Score 41     35.0 113 6.0 Used
  Practice Score 40     36.0 113 4.0 Used
  Practice Score 41     35.0 113 6.0 Used
  Practice Score 44     36.0 113 8.0 Used
  Practice Score 39     35.0 113 4.0 Used
  Practice Score 47     36.0 113 11.0  
  Practice Score 43     36.0 113 7.0  
  Practice Score 50     35.0 113 15.0  
  Practice Score 40     35.0 113 5.0  
  Practice Score 43     36.0 113 7.0  
  Practice Score 40     35.0 113 5.0  
  Practice Score 39     36.0 113 3.0  
  Practice Score 42     35.0 113 7.0  
  Practice Score 43     36.0 113 7.0  
  Practice Score 36     35.0 113 1.0  
                   
  Only the last 10 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...          
  7.0+4.0+10.0+5.0+6.0+6.0+4.0+6.0+8.0+4.0..etc.. = 60.0          
                   
  Then divide by the total number used.          
  Pre-Handicap = 60.0 / 10 Pre-Handicap = 6.000          
                   
  Thom is a regular player, so according to the          
  handicap setup the Handicap Percent is 80          
  Handicap = 6.000 x 80   Handicap = 4.80 (Digits after hundredth place are deleted)  
                   
  Convert the handicap to a 'course' handicap using the slope of the course being played. (Prairies Front)
  Handicap = Handicap x (Slope / 113)          
  Handicap = 4.80 x (117 / 113)            
  Handicap = 4.97              
                   
  Final Handicap = 4.97
