That I don't know. I don't know if descriptions of the Usability Initiative's studies are all public, or what. Maybe one of them could fill us in.
There are videos around, yes, but I'm not sure we have reports. Digging around on usabilitywiki should turn stuff up, or maybe someone closer to these tests (both geographically and in terms of expertise) can provide more exact links.
The tests were specifically focused on editing and general navigation, and did not test the history view AFAIK.
