New PIP Form

Hi there, I've recently been successful in the completion of my ESA claim review(thanks to your guides as usual)
It's only been about a month but now I've received this new PIPs award review form titled "Making sure your reward is right" even though my current award lasts until May 2019.
This form is set out so your answers are either your conditions are for e.g. eating and drinking- tick boxes easier, harder, worse then some room for more details.
I'm just wondering if you have any guidelines on this form?
Many thanks Pauline

Thanks very much Gordon, I'll read over the PIP guidelines again before filling this form in.
