   Leaf counts are always going to be system dependent.  So in your "other tables   
   and stats", instead of giving absolute leaf counts, give an antiderivative's   
   size relative to the optimal's size.  Then both sizes are measured using the   
   same leaf count    
   function.     
      
   This is more useful information for users than the absolute size.  For   
   example, your overall test summary could say Mathematica's is on average x   
   times the size of the optimal; whereas Maple's is y times the size.
