I'm afraid there are a couple of problems with this analysis:

- Automated bugs (eg from abrt) may or may not be considered to be
  real bug reports.

- Bugzilla has both imported large bug sets from other databases at
  various times (when Red Hat acquired other companies), and also has
  had periods when it didn't allocate bug numbers sequentially.  At
  one point IIRC each new bug report incremented the bug ID by 10.
