The answer is found in the eyeball integration of the graphs on:

     http://setiathome.ssl.berkeley.edu/dgraphs.html

At best, the number of new work units being generated per day is 150,000
(with a more reasonable estimate to be 80,000).  On the other hand, the
number of units returned per day is holding reasonably steady at 300,000 per
day.
