Yeah, I misspoke.

This is because I shift the 'archived bug' data by 28 days. I'm not entirely
certain this is correct to do.
However, even ignoring that, the rate of growth of the graphs still show them
converging.

So what else could you conclude? The total number of bugs(green) is very easy
to validate. So is the number of archived bugs(red). Both can be verified by
using find|wc.
I do no categorization, outside of active/archived. Both directly correlate
to /org/bugs.debian.org/spool/{db-h,archive}, respectively.
The algorithm I used is:
* load all bugs, active and archived:
* as each bug is loaded, do a date -= date % 86400, to round all dates down to
the current day.
* Additionally, for the modtime of .log, add 28 days.
* sort this list twice:
* by last modified time of .log
* by the open date, as recorded in .status.
* step thru the .log list, by day.
* For each stopping point, find the same point in the open sort
* add the current pointers to a stats list. Also, add the delta from the last
round.
* save the last 366 items, and send thru gnuplot.
Please see master/~doogie/debbugs/graph-stats.pl, which saves data to
graph-stats.out, and the gnuplot 'program' in graphit.

No, because you are excluding bugs.
My graph includes closed, but not archived bugs. A closed bug is still
active, as it can be kept going, and still reopened, until the magic 28 day
marker passes.
