Rather slower than you lot on this one - but distracted by other things over the weekend. Whilst I could pick an obvious phrase out of the 21 letters early on, it took me ages to figure how to disappear the redundant letters, and meanwhile became very distracted by 17dn and the first 3 letters of the top left diagonal - anyone else spot that - and wondered whether there was a sub-elitist element as well. I'm afraid I had to Google the second 4-word phrase to discover its relevance. But yes - many nice PDMs.
As to statistics - I don't think that they are normally posted until after the famous Dinner, which is this weekend I think. So presumably there'll be an invitation to mail your SAEs in the next couple of weeks.
