Number of bugs worked on

Hello,
How can I see the number of bugs I have worked on?

I started bug triaging 3 months ago and have been working to clear up old bug reports.

Steps I use to calculate my personal stats:
1. In my profile page I go to advanced search,
2. Select all statuses
3. Under "commenter" box, I select "pick Me"
4. Click Search

Expected results: it should show the number of bugs I have worked on (left comments on).

Actual results: the results total is much higher than expected. It is counting the number of packages in each bug.

For example, if I work/comment on 1 bug report that has two packages associated with it, the search results counts that as two bugs.

As of today, my personal total results according to Launchpad is 1,747 bug reports
My estimate is the total should be about 1,388 bug reports

Is there any way to see the total number of bug reports I have worked on?
Thanks
G
