Re: [office-formula] Formula Terminology

So if we say "should" in a constraint, is that an example of  "unless 
otherwise noted"?

I hope not, since that would be rather subtle. 

Stating the behavior once is fine, so long as we're consistent in doing 
so.  Randomly repeating ourselves suggests significance that is not there.
