superseded decision, Implications resultiing from

As we know, the mandatory reconsideration decision will supersede the original decision, sometimes not in a positive way, but I'm just wondering, In the MR they have now included items I pointed out ( items in our favour ) that wasn't mentioned in the original DM report to bolster their decision on the original dismissive report. these would be items like having to hold onto items of furniture etc for balance to do the requested tests for the HCP. This was not unexpected but now creating a little extra work here.
My question now is, at the tribunial can i use any of the original decision for appeal or have we to go wholy on the MR decision ?
AT the moment we have gone from ehanced to nothing so basically nothing to loose but everything to 're' gain

Holding on to furniture was in the MR to say she could do tests for HCP whilst holding onto them but not mentioned in the original decision where she tried to do the tests and not mentioned.
To me, one would suggest she did the tests unaided but on the MR did so with support to retain the original decision.
Like i said, a little extra work for the weekend then appeal sent off next week and just a case of wait and see.
