   performance - not the best, not the worst    
  Enter number of weeks the park is open each year  
   You can enter the following park performance numbers as either revenue or  
   head count - but you must be consistent    
  Enter the park's BEST Saturday performance in the past year  
  Enter the park's BEST Sunday performance in the past year  
  Enter the park's TOTAL Saturday performance over the past year  
  Enter the park's TOTAL Sunday performance over the past year  
  Enter the park's TOTAL performance over the past year (that is  
      Monday to Friday and weekends)    
  Calculated Saturday slack   
  Calculated Sunday slack
