Upsetter, there are two of us and we are 'middling ability' solvers, and, even though we had the source after about an hour (which, of course, didn't at that stage help much except suggesting the endgame long before we had a full grid) we were solving for nearly three hours. That, for me, makes a fair Listener of the 'easy' end of the scale. The lovely, unambiguous endgame (with the slight hitch, for some, of a variant in all earlier versions of ODQ but it is totally unambiguous in Chambers - which is, of course, the recommended source) added brownie points.
You know I am a setter (obviously from your charming comment) and I would say that it is difficult to fundamentally shift one's level of cluing difficulty. The Sharks, Elgins, Sabres, Quinapali, Ilvers, Artixes and Wans of the crossworld will continue to be Magpie D and E setters and the Chaliceas, Samuels and Nutmegs and probably KevGar will enjoy filling the Magpie A, B, C slots. (Magpie plug - there are always six more challenging crosswords available for anyone who suffers from our crossword obsession and has time to fill
http://www.piemag.com) but I am convinced that the editors have got it right in admitting the full range, as long as the unching, word-length etc. fit the rules.
Expert solvers like you, Starwalker, Trux, A Hearer et al. have to live with mild disappointment sometimes, knowing that we will all be seriously challenged by next week's or the one after it.
I agree that if a grid is filled by us in 30 minutes, it IS too easy for the Listener (and there have been a few like that over the years) but I am sure the comments that accompany entries to JEG for this one (they are forwarded to the setter) will be very positive in general.
By the way - your comment about remuneration; I set weekly for a national newspaper and the other Numpty (yes we are the Numpty bloggers so do have an obligation to solve all the Listeners) commented, not long ago, that the 'hourly' income from it is below what is earned by Her Majesty's guests at, say, Pentonville, if they 'work'. I would say that at least 100 hours probably go into the setting, responding to vetting, working with editors, proof-checking etc. for a Listener crossword - some fellow setters might say it is twice that - so clearly it is a labour of love.
