       According to what I've read, some people consider the DOF markings on 
most                   lenses to be a bit optimistic, and prefer to take a 
more conservative approach.  In your example, with the lens set at f16 they 
would use the f11 marks on the lens.  This is what I do, particularly if I 
think I might be wanting to make a large print later.

 Well two questions, does that mean the furthest distance in that range is the
 hypofocal distance? >>

          The hyperfocal distance is the distance that actually falls at the 
focusing index mark when you set the DOF scale to give you a range to 
infinity on the far side.
