   I presume you are not actually asking me to prove my experience   
   as a grad student actually existed. :-)   
      
   Any other relevant proof - such as it is - could have been fairly   
   easily found by following the doi's (and references therein) in my   
   post. So, in answer, what I might claim to be "pretty sure" of is   
   not an opinion, but actually derivations you can go check. Feel   
   free to raise any queries (or disagreements with) here and I'll   
   try to answer them.
