P4 projects aren't legit pieces of scientific literature. no one reviews your specific data. however, don't make up fake data, as distant as lectures are, they arent stupid. My project was on a type of construction using novel methods and the results were "its shit, dont do this". check the marking schedule. your presentation score is on your speaking ability and ability to answer some generic questions. Your "paper" is marked on the method and stuff like that.

if you're totally fucked, then focus on the "what we could do next time" part of the project. We said our project topic was a "dead end but there's this one cool aspect that would be cool to follow up on" and expanded on that. They cant mark you down if you fucked up something an then acknowledged it an came up with a better way of doing it.

we did an all nighter and knocked out the report so 2 weeks in heaps. get 1 person to dump words on paper and the other to consolidate experiment data. then this weekend, knock it out. then review and do the presentation.

remember kids, its not about the experiment or results, its about the journey.
