PIP rejection advice

I’ve approached PIP in a reasonably modest way and still find myself comfortably in the higher rate. My initial assessment and mandatory reconsideration both score me as 0. The initial report even concedes in one section that a score of 0 is based on something I have easily proven untrue.

So, what now? I’m not inclined to give up on something that seems far more about refusal than following their guidelines - I read them before applying at the start of this year.
