Careful, that paragraph from my post has *quotation marks* round it ("), 
I was quoting it in order to disagree with it. If they test the same in 
all respects, they look the same. I don't believe that any modern quality 
lens manufacturer has production variations which affect the look enough 
to be seen by the naked eye, and if they do, their manufacturing process 
is knackered!

People see the differences *IN LENSES WHICH TEST DIFFERENTLY*.
