Wow.  You've earned yourself another Graham Kiss (tm).  That's
incredible.  This is precisely what I was hoping in my wildest
dreams that somebody would do.

I've uploaded the factual analysis, and csv file, to the page:
http://lilypond.org/~graham/gop/gop_4.html


A challenge for somebody else (because Carl has done enough):
produce 1 or 2 graphs that visualize this.  Note that producing a
good graph is not just a matter of picking two columns and
clicking through a wizard in excel; I'd budget at least 30 minutes
on each graph.

My first suggestion would be to try:

  X axis: dates
  Y axis: bug open, bug closed
  plot lines from open date -- close date.

We should see a whole bunch of 
  / || / _/
 /  /|/ /

lines.  Use a light color, because I think that when we're dealing
with 148 separate lines, the overall density will be more
important.  (oh yeah, make that light color by playing with the
alpha color value, so that multiple lines will produce denser
colors?)   It might need to be done with a relatively high
resolution.


I don't know how informative such a graph would be, and I'm pretty
certain that wouldn't be the best representation, but I think it's
a decent place to start.

Cheers,
