  Bob, 
     I believe the correct way of giving the anwser should be: 
      NO!  It does not "keep going" with DR.
   
  I saw the beauty of DR immediately, as you described it.  (still learning about APRS & your work)
   
   It does not "keep going".  The display gives a definitive indication of a "stale" target and an indication of how stale or latent it is...at a glance.
   
  Beautiful.
   
  The other side of this, of course, and as you are well aware of, is sensory overload...if you try to cram too much info into a given space / screen / ear.
  On some of those high end flight simulators, I sometimes wanted to shoot that damn babe relling me for the twenth time I was hit.  "Shut the bleep up!"  I'm trying to fly the damn plane! ... and save my ass!"  (:-)
   
  Good thing it was just a simulator...
