  Bob,
  
  Thanks for the information but frankly you're over my head. I'm just a
  physical chemist with little metallurgical training and even less in the
  intricacies of these engines. I'm simply pointing out, we as owners and
  users of expensive machines, should rely on empirically derived decisions to
  save our hardware rather than theory or OWTs.
  
  I would never recommend coming to idle at 20,000' (or any very cold
  altitude) as a reasonable method of loosing altitude -- and I think all on
  the list would agree. I think all of us know gradual and calculated changes
  in our aircraft operations are preferred in all our activities excepting
  emergencies.
  
  Clearly your knowledge and experience of this subject is above my
  understanding. Thanks for sharing it with us.
  
  Jim
