PIP - what next?

Just before Xmas I was awarded the enhanced rate for my daily living needs, and also the enhanced rate for my mobility needs, 24 points out of a possible 84, and 22 points out of a possible 24, respectively.

With the undoubtedly good news of this letter they sent me a booklet: Understanding Your PIP Assessment, which has a FAQ section, of which the first Question is 'Can I have a copy of the assessment report?' to which they answer in the affirmative giving a phone number to call.

I'm thinking that all of the above is familiar to you all.

My question is that given the narrow margin I was able to be awarded the enhanced rate for (especially my daily living needs), that it would be unwise of me to question how exactly they were able to find in my favour? What do you think?
