pip point for activities

I am preparing for a tribunal and going through points allocated. My question is this; should points for an activity be given for physical and mental conditions, then added together as a total. For example; preparing food 2 points for physical disability using an aid = perching stool. But due to depression, sleepiness due to medication, and lack of motivation. I could try to cook something and fall asleep whilst it burns, or not have the motivation to cook at all and order takeaways. could I say get 4 points for needing supervision due to depression totaling 2 + 4 = 6 points in total for that activity. then other activities considered in the same way.
