Mandatory reconsideration

May I ask for some advice? Thank you.

I have been awared PiP (so happy) and not yet recieved my award letter. I asked for a copy of my PA4 report within two days of medical and it was lost in the post had to ask for it again it arrived today 2 weeks after first requested. The decsion was made to award before I had sight of the PA4. From looking at the report and the descriptors awared (ticked) I have been awarded no points for the '11.Planning and following journeys' yet I belive my evidence should have been awared 8 points which would move me to the enhanced award for mobility. The assesor says because I can manage short (familiar) journeys and wasn't showing signs of anxiety, had a normal manner and coped well with the interview I should be able to plan and follow an unfamiliar journey. In my application and interview I explained why I could not do 'unfamiliar journeys alone' and its mostly physical as well as mental. I also prepped for the interview and am used to speaking in public and my nerves/anxiety do not always show! The comments about how I presented are all subjective.

The assesor was very pleasant and said I could add any comments if I felt her report was incorrect, before the decsion was made, but it arrived after the decsion was made (was made very quickly) so I wasn't able to respond as I wanted to - it was too late.

I feel I will want to ask for a mandatory reconsideration to try for the enhanced mobility rate but I see the success rate is low. I also have seen my GP since the medical assesment and a few things have chnaged. I feel I have enough evidence to challenge but is it worth it and do I risk losing the standard award?
I have had so much help here from the guides, the forum and researching all your responses to questions.. I thank you all so much! Thank you for taking the time to read this.
