Earlier, talkin, I said: "About 'types' of GS: I am not opposed to the existence of a few, highly specialist schools for DCs -ahem- burdened with the SEN of being extraordinarily gifted but with off-beat social or inter-relational skills, 'oddball' but brilliant (in the same way as we have specialist schools for DC at the other end of the more or less NT spectrum). I'm thinking of, say, Winchester College where being 'just clever' (and rich!) isn't enough. You have to be off-beat, quirky, a bit 'other'. Mainstream public-school heading 'clever' go to Westminster and St Paul's (generalisation alert!). I can see a need for state school DC who'd fall into this 'quirky and very clever category to maybe be siphoned off into something other than the local comp, but as for the rest (and I mean, hey, if we're talking '23%' of the DC' as quoted, hardly a glittering, tiny, special minority, is it?!), a well run, properly resourced comp should be the destination of choice. I would add, entry to such a specialist school would not be via a single exam on one day. There would have to be years of evidence of this DC's particular abilities. It would be utterly 'untutorable' for."
And if we're talking 'normal GSs' that take 'the top 23%'- well, the reality is that if you took 100 random DCs and ran an 11+ exam on them, it surely can't be argued that the DC who came 23rd out of 100 is so amazingly better than the DC who came 24th, yet the current (non-SS) selective system would have those DC separated by geography, uniform, learning style, aspiration, opportunity and so forth, possibly with effects reaching into their old age. And also, surely coming 23rd out of 100 doesn't actually make anyone 'super-bright', does it??
