To say that you will "Stanwoodize" without specifications is not applying 
David's
system, and as such should not have his name attached to it. David's system 
is a
calculated process and to lend his name to a generic 'rewhatever' is 
misleading,
as unintentional as it was.

I'm certain David would like his process to be well known with everyone but 
would not
appreciate the loss of product identity through casual lingo. Some product 
names have,
through casual usage, replaced product nomenclature; Bandaid for adhesive 
bandages,
Kleenex for facial tissue.  It would be a long time before "Precision 
TouchDesign" or
"Stanwood" becomes a household words but to infer David's process for general
action geometry modification is completely incorrect.

I understand Richard's enthusiasm and interest in action optimizing, I just 
want to
clarify terminology.

Get on board...  get the lead out   :-)
