Yes, but as I wrote in that Signpost article, that data relied on the gender editors state in their user preferences and "this information is optional and the majority of accounts do not state it". There a good reasons to assume that the differing incentives distort that data even more than the anonymous responses to banner-advertised surveys. For example, the user has to be comfortable with stating their gender in public, and in several languages female users have to set that user preference if they want the word "user" next to their nick show up in female instead of male grammatical gender form (e.g. "Benutzerin" vs. "Benutzer" in German) - male users do not have that incentive.
