I have never heard of Elmhurst Primary School, nor Dr. Jonathon Solity.
But I am aware of the UK Medical Research Council, and it is their figure that 10% of children have some degree of APD, not mine.
The issue is about the cognitive skills required to perform the task of reading, and if a child is give adequate support to develop compensating cognitive skills to work around any auditory processing deficit may have. This can not be done when using any phonics based program. This is not about eventually being able to read, but how a child learns to read, and how a child is provided with the cognitive skills they require to work around any cognitive deficits they may have. many who have APD learn to read like I did despite phonics, having to develop our own methods of reading based on our won version of a whole word approach, while being called stupid by peers and teachers because we can not use phonics.
And teachers are not able to define how any child actual learners to read, as they are not able to carry out the required neuroimaging which can identify the areas of activity in the brain when performing the task of reading. So they can not say which type of program is most suitable for those who may have an information processing deficit. So you you can not possible have any scientific data as to how children actually learn to read, you can only make assumptions or guess.
And it is in your own interest to distort the data in favour of phonics, and until there is an independent Educational Research Council, run on similar line to the Medical Research Council there will be no realistic data on these issues only marketing material to support the sales of the various programs each provider sells. And you are very closely associated with Ruth Miskins and her marketing needs.
International research has recognised the need to use both phonics and whole word to develop the various areas of the brain involved in the task of reading, both the lexical and sublexical functions. While those who are not able to use whole word can focus on phonics, and those who can not use phonics can focus on a whole word approach, and there may even be others who need a more kineasthetic teaching method. This is about finding the teaching methods that best suites each childs learning needs, which can vary according to vary stages of the cognitive development, until the age of 7 - 8 years of age, The age of maturation.
This is about not having a one size fits all, which is statistically impossible, although you do your best to distort the figures.
I know how you hate reading research papers, abstracts and following links to bodies of international scientific information. But i will provided you with two links not that you will ever follow them. To two of my online PubMed research paper collections, (where each paper will always have links to more related papers)
My PubMed Reading research paper collection (which includes 208 research papers of which 42 are Free Full Text and others may be available at Google docs)
and My Dorsal and Ventral Streams - functional anatomy of language collection (51 papers of which 7 are Free Full Text)
Unfortunately we do not have the same quality of research advising the UK education system and providing the understanding of our children cognitive learning needs. We have mainly lobby groups, marketing hype, and the old wives tales of "what works", no real scientific research at all.
