HF L/S Case Questions (Operating Cases and Quarterly Projection Period)

Had a few questions for an upcoming case study which I think are broad enough to be helpful for others:

• For a timed case study that only lasts a few hours, does it make sense to model in specific operating cases?
• If you are building a quarterly projection period, what is typically a good projection period to model the company out for or do you stop at the point when you're asked to provide a target price?
• If the instructions are to only use the Ks/Qs to build the model, how can you arrive at a share price target without comps? I assume for the most part all HFs think a DCF is not meaningful, especially since the filings don't give the data which you need to find the WACC.
