I see your points.  Back to what M. Fatih Köksa seeks, "to measure the  
effectiveness of proper usage of Design Recipe."  I now realize I  
misread his question.  I imagined he was trying to measure the extent  
to which people were following the recipe properly.  Now I read it  
differently, that if the Design Recipe is properly used, what is its  
effectiveness?  That makes me wonder, against which other approaches?
