Maybe other members will have some ideas of questions they asked or wished that they had.
The assessor will be following a script so there is little room for them to reduce the assessment time and it may not be to your advantage to hurry them along as it may mean that they do not pay proper attention to your issues.
If they ask you to get out of your chair and you can manage to do so then just tell them this and explain why you can't
You might want to have a look at the PIP Claim guide there is a section at the back that covers the assessment and the questions you are likely to be asked.
