   Yes, it is appropriate that you are using MmaTranslator:-Mma]:-LeafCount   
   instead of the `length` command on Maple.   
      
   Here's another reason why that is so:   
      
   length( aaaaaaaaaaaaaa + b );   
                                    22   
      
   length( a + b );                
                                     9   
      
   But it is important that your grading scheme measures the size of the   
   "optimal" anti-derivative using the same system as for the measurement of the   
   result.   
      
   For example, if you use Maple's own `LeafCount` to measure the size of an   
   integration result, then you should very much also be formulating the optimal   
   result in Maple as well, and then comparing by computing the size of that   
   optimal result it Maple. You    
   must never compare against the optimal size as measured by any other system.   
      
   I suspect that Albert's has made the same point. I'd like to stress it. If   
   that is already your approach then apologies for mentioning it.
