Re: [CVEPRI] Increasing numbers and timeliness of candidates

For reference and further discussion, here are some usable statistics
that show what's been happening.

Column 1 is the date on which the candidates were proposed.

Column 2 is the number of candidates that were proposed on that date.

Column 3 is the number of candidates that had been publicly announced
between 0 and 30 days before they were proposed to the Board.  The
other columns represent other date ranges.

In early 2000, I was clearly focused on handling new issues.

As the volume increased to 100+ CANs (Sep 2000 and on), the 31-60 and
61-90 delays started increasing.

The total number of issues being proposed within 0 and 60 days was
pretty high during the first half of 2001, when we were processing
legacy submissions in addition to handling new submissions; new
submissions were a higher priority.  During Summer 2001, the number of
0-60 day issues dropped dramatically as we focused on the legacy
candidates.

September 2001 is obviously the legacy candidates.  The efforts to get
the legacies out caused a backlog in the more recent candidates.

The remainder of the stats show the impact that that backlog had.  We
started generating many more candidates per month to catch up.  We are
producing at higher rates than we did before, especially in the last 3
months, but the backlog was dragging us down.

Our output has increased dramatically, but we have not been able to
achieve timeliness like we wanted to.  I believe that the bulk of the
backlog is gone, so the numbers should start moving to the left,
although the next few months may still see considerable numbers in the
61-90 and 90+ day range.  However, we are (fortunately) producing
content on a monthly basis that exceeds the current monthly rate of
new vulnerabilities.
