Looking it from the other end, which sites did not hit, all I see in our neck of the woods is zero or shallow content, often not related to the query, in the top 10, and always the same sites using a template. In fact I might as not bother with content..
Given the above , which may be to skim them off, and a few other signals I am getting, I would anticipate a further tweak very soon.
Time to recover - possibly never at the moment.
Nice data Content_ed, thank you for taking the time.
