Just my opinion as I have no personal experience of QM allocations.
It would seem that your DD would have gained a place at QMHS for each of the past three years based on her ranking, which is well above the last allocation ranking in previous years, and as there are an additional 16 places available this year then the chances of her gaining a place on 1st March are, I would imagine, very good. There are obviously no guarantees though, especially as this year is the first year that results were available to parents before completing the CAF and no one can anticipate how that might effect the allocations. However I agree with AliceM that candidates would have had to have expresed a preference for the school on the test registration form to have been included in the initial ranking for a particular school, it would not be enough to just have sat the consortium test.
Good luck to you and your DD for 1st March, I'll cross my fingers for good news for you
