Molio - you keep flipping around, trying to make "contextualization" out to be all things to all people. That, I think, is the whole problem.
It is this muddle which means many Colyton kids do less well with uni admissions than should be the case, given its admissions base (C gives one place per three applicants and the applicant base is unlikely to be an average ability group to start with).
I am not complaining about Colyton!! If you are characterising me as such, you are not reading what I'm writing.
I do not believe the bulk of C's kids are given a fair crack by the system of uni admissions, and my evidence is simply the admission stats and destination outcomes, plain and simple. Everything you say seems to make this point for me.
Your direction now is to start digging into another school, an Exeter private day school this time, and getting very chippy about privilege etc.
I know kids currently at Exeter, the Maynard, Blundells and West Buckland, amongst others. First, I don't see that those at Exeter are "overwhelmingly privileged" at all. Some are on entirely fee scholarships and rub along perfectly well with those from much wealthier backgrounds. Undeniably, the Exeter kids are not more privileged that those I know at the other Devon privates; and yet Exeter, together with the Maynard, produces exam results in an entirely different league to those achieved at Blundells, West Buck, Shebbear, Kelly etc.
My personal impression is that the kids I know at Exeter are more booky and competitive than, say, Blundells or West Buck. This corresponds with what several other posters have said. There seems to be a range of choice for parents if they can afford the fees or access a rare free place. Me: I think that's a good thing.
I think it's a disgrace that the state system in much of Devon just stumbles along, denying real choice to parents and opportunity to kids. As other posters have said, this is why so many MNers are driven to look at the private sector. Many families make huge sacrifices in order to give their kids a better chance. It sickens me, frankly, to hear their kids labelled as "overwhelmingly privileged". What the Maynard and Exeter kids seem to have in common with those at C is the privilege of having educationally supportive parents.
But you also seem to be saying that Exeter, too, does less well in uni admissions than one might expect given its selective nature (it's hard to know how selective such schools can ever be, though) and its exem results. Which way is it?
What I think you are doing, Molio, is showing everyone who reads this thread that there is thick a layer so-called 'progressive' fiddling which stands between many DCs at good schools and their chosen uni places.
Your sneering about Exeter is as unpleasant as it is unfair.
Grammars-aside, if the state schools in Plymouth, Barnstaple, Tiverton etc were any good, then parents and kids at state schools there wouldn't need to rely on the system being stacked against the likes of Colyton in order that they can go to uni.
