At http://korma.wmflabs.org/browser/gerrit_review_queue.html, under "Ranking of repositories", there is a column for "Waiting for review". These minicharts should show how many changesets open for review (no -1, no WIP) were every month.
I have just realized that what is shown is actually when the *current* open changesets were added. This is why all graphs are incremental, there is no graph showing lines going down.
For instance, the TorBlock minichart showed 3 changesets just a week ago. After pinging a couple of people now there are only 2 open, but now the minichart shows as if there were only 2 open all along. It should show 3 en July, and then (if nothing changes) 2 in August.
