You are coping with major challenges Pemberley and are obviously working hard to support your DD while trying to find ways to also expand her strengths. It is very good that there is an attempt to accelerate your daughter in her area of strength.
Such a complex profile would seem to be an explanation for the spread of her results. What you really might want is an underlying unifying diagnosis. I can't begin to help you with that but would second the suggestion to keep an eye on any physical causes that could be impacting. An endocrinologist can help with some of those particularly thyroid, pituitary and adrenal issues. Not saying there are any but such things can be missed so always wise to check in especially as she also has migraines.
I came across this article on slow processing speed.
