PIP Renewal form 1043

Thank neptuno. I thought I was going mad looking for AR1. 1043 is the form. I had hoped there would be general advice on filling this in. ie If all sections are ticked 'No Change' without any comments, how DWP would rate this. Is it better to actually better to put some sort of comment in there?
Are they going to look at original application, or do I have to reiterate problems?
I only have 5 days in which to complete this so any advice would be welcome. I know there is lots of stuff on here for completing PIP for the first time, but very little for 1043.

Thanks Gordon. As this is a new form, we need all the information possible. When I get a response to mine, I will add feedback.
