Clearly that was not the intention BigDave and I think you know it.
To be honest, having read the OP’s post, I don’t know what his intention was/is!
By stating ‘By group I mean those that get the full Motability payments via PIP’ it appeared to be defining ‘group’ to a specific set of individuals, regardless of the fact that the Motability Scheme is open to more than those that quote ‘ get the full Motability payments via PIP’.
It may have better served the purpose to have just used the term ‘Motability customers’!
