Well, I think you've got the formula correct but I still don't think 
that justifies testing beyond what you actually intend to use.  So what 
if a slow B&W film yields 120 lines/mm but you only ever intend to use a 
color film with resolution of 60 lines/mm.  I'm looking for the "why do 
you care" answer.
