   OK, so what you (and all the sources you are quoting) are saying is that   
   brake discs *don't* warp by any measurable amount because they are designed   
   not to do so and must conform to a standard that means they don't.   
      
   And when people feel their car juddering (and maybe the pedal vibrating)   
   during braking, that's not caused by a disc which is "warped" in the   
   conventional sense of "not a plane disc but one which is wavy like a potato   
   chip", but is instead caused by the surface being more or less "sticky" in   
   different parts because of local roughness and/or glazing from pad deposits?   
      
   That all sounds very sensible. I think you've settled the debate by quoting   
   sources. The problem is that there are also sources which still use the term   
   "warped discs/rotors" to describe discs which have localised   
   roughness/glazing. That word "warped" is misleading because it makes people   
   think "wavy".
