Problems with the models. How many to use?

Hi all! I have a question to those who got B or A from the project. How many models have you used in your RAP? Currently I have used: 5 Forces, SWOT plus financial ratio analysis. My mentor told me to also add PESTEL. I am very confused whether I should do this because the more models, the less analysis. So I appreciate any tips from your side.

I would like to mention that I am doing topic 8.

Many thanks for your help,
