My experience is that 
   1.  Taken across a very wide sample, people seem to be able to
      write/debug betwen 100 and 200 SLOC per month.  This has been the
      "going rate" for about 20 years, or since we started measuring code
      in SLOC/unit time.  
   2.  There is a very wide variation in the productivity of individuals.  Some
      individuals produce 10 times more code than others.
   3.  Ada doesn't change the rate of production much.  But it does change
      the allocation of effort. You spend more time designing, and less time
      coding and particularly debugging.
   4.  Ada starts to provide "a win" when integrating.  In particular, Ada 
      systems in the 10k-100k SLOC range seem to go together quite smoothly.
      Above 100k you have to have additional tool and procedure support.
