Symbolic, with some help from Oscar, has now finished over 5% of the needed results. Arkan has produced another 20+% of the results so far, and in future status reports I'll include more summary information about the merged effort.

New links for weekly status reports
New links for weekly status reports; now organized by year.

Note that while production mode started on a Friday (2014-08-08), each weekly report carries a Sunday date. There is no good reason for this. Also, there is no detailed data for reports 2014-08-10 to 2014-09-07 inclusive. There is no good reason for that, either.
