Sally, I understand that lots of sites were not judged at all by panda for various reasons - eg site age and size, subject matter, commercial intentions of the site and appearance in serps for commercial terms might all have helped decide which sites were assessed.

So having a high 'advanced' rating for some sites not affected by panda is quite predictable.

In any case reading level would presumably only play a part in the overall calculation. I'm not personally planning on dumbing-down 500 articles in an effort to escape panda.

It is interesting to consider whether a machine trying to judge the quality of a page would conclude that an article with long sentences, excessive punctuation and lots of long words (presumably the main factors that constitute 'advanced reading level') would in all probability also be a poor quality article, for example because spam, spun and auto-translated page share the same attributes.
