     does anyone have guidance on this timing?  perhaps 6-8 years after
     initially coming under scrutiny?

   I have no specific knowledge/experience, but I'd say that you could use
   "FOIA attempt" data to construct a pretty good "FOIA completion rate"
   over time picture. Maybe repeating some older FOIAs can lead to
   interesting completion results."Delays" would also be very variable,
   depending on police investigations. But probably normally distributed.
   Ultimately Data wins! And probably nothing else :(
