Like you I'm at a complete loss.
Our EMD has not shown any sign of recovering, but we've not tried any changes.
It's not a site that brings in money and at present we are trying to reverse the trend on our money sites where there is a greater increase in Adwords spend for far less conversions...but that's going a bit off topic.
We have a number of PMD ecom sites that have slipped down the rankings because well known brands that were never in the top few pages have taken over the first page of our SERPs.
