I do not.

However, I was on the Committee that awarded Dr. Joseph Bonneau the
NSA's "best science of security paper" for 2012.[1]  His work, in
case you are not already familiar with it, was done under the
supervision of Ross Anderson and is entitled "The science of guessing:
analyzing an anonymized corpus of 70 million passwords" and can be
found at [2].  If you are perhaps thinking that doing the same study
again but on the Adobe corpus, then I'd be eager to read what you
come up with, to be sure.  Bonneau's paper is certainly careful and
detailed enough to enable a confirmatory study.
