Correction made to Successful PIP Tribunal Judgement

This is very last minute as if I should ask for a Statement of Reasons it needs to be today! I won my appeal on Mobility Descriptor 1 that 1f applied to me on the basis that it is a physical problem I have as a result of several outside stimuli. This will happen with my walking sticks however if I have a human companion to hold their arm I can manage. I received a letter saying that the Tribunal was asked by Secretary of State i.e. DWP to make a correction that I should have been awarded under Mobility 2 descriptor 2f. I wrote to pint out that entire Tribunal discussion cantered on 1f . There was a representative from DWP also there and he agreed with the decision on the day. I also pointed out that corrections were supposed to be for slips of the pen. I received a response following a review by another Judge to say correction stands and ( in effect) why was I concerned as the outcome was the same i.e. 12 points. It was also made clear if I ask for Statement of Reasons I am opening up the door for the DWP to take case to the UTT. My concern is that while on more than 50% of the occasions I will have the physical response that stops me for example crossing a road I can then do so if I take someone's arm. I do have difficulty walking even aided however I can walk more than 1 metre especially if I have someone with me. Is there any point asking for SoR or do I just accept that because the rigidity can happen I therefore fit in to 2f? Award was made for indeterminate timescale. Advice from anyone who has the Tribunal experience or experience of a similar correction. I have no problem arguing a case at Tribunal but really life is too short to be constantly looking at this.
thanks
