Are Wikimedia's staff and non-staff contributions processed equally in Gerrit?

To answer this question we need to cross the "Average time to review" data http://korma.wmflabs.org/browser/scr.html with the affiliation data from http://korma.wmflabs.org/browser/contributors.html

Currently we have these affiliation entities:

Wikimedia Foundation
translatewiki.net
Unknown
Independent
Wikimedia Deutschland
WikiWorks
omniti
wikia

We want to know whether there are significant differences between e.g. WMF and independents. We also want to know whether those differences evolve over time.

A graph of points and lines should be enough. X are quarters and Y is time to review.

Not sure how to represent quarters where an org had no commits reviewed. "0 days" would look like "very fast".
