strange questions about time at my PIP review today

I had my PIP review today, by phone call as I do not have facilities for a zoom call. I had been waiting for over a year and I had enought points already for the lower award under mobility.

As my conditions, both peripheral neuropathy and arthritis in my feet has got worse since my claim in 2017 I asked that they increase my award under mobility to the higher amount.

I was ready with my answers about distance I can move and pain and repeating the activity etc- you know.

But I was not aware that I would be asked questions about the time it took me to

Walk across the kitchen
Walk from the front door to my car
Move from the kitchen to living room.

Any idea what was going on here and why was I asked these questions?

Thankyou Biss,

I had a message from the DWP saying they had received the assessment. I will request the PA4 report, like I did at my original claim. Can I make this request by email or do I have to phone them? Do they still send the PA4 in the post or will they e mail it to me?

Thank you
