If anything, we had the opposite problem. The pandalized sites that didn't recover were 16 and 11 years old respectively and each included a number of major subject areas that were entirely unrelated to one another.
The 5 ways to pick your nose is typical of article farms. In our case, we have small numbers of deep pages that cover everything we have to say about a subject and have always been cited by people and media as authoritative. Of the current four sites, only one has more than a hundred pages. Prior to breaking them up, the main business site had around a thousand pages, but most of those were my personal blog.
So no, doesn't fit my experiment, exactly the opposite. You might want to read through from the start of the thread for the full description, these are just my bi-weekly follow-ups, I'm not trying to describe the whole thing in each update.
You may have missed that the numbers of pages involved here are tiny by the standards WW users. And, as I commented in the last post, they are some of our most authoritative pages. Many of the pages 301'd had each attracted links from hundreds of different domains. Given the subject area, it doesn't get any better.
