Even though the rules say that each adventure provides guidance on the number of Requisition Points they provide, I can't find it in the "Extraction" scenario provided at the end of the core rule book. Did I miss it, or if not, what is it?

I didn't find any guidelines for it, but as I've increased the difficulty a bit for my group, I gave them 15 each.

As this is a beginner's mission, I would rate it this way:

21 (novice primary) + 16 (novice secondary) + 4 x 6 (novice tertiary) = 61 requisition points for each battle-brother (4 tertiary's should be enough). Round down to 60 req.
