I've been going through the camping rules and trying to create a flowchart. I noticed that the camouflage campsite activity states explicitly that it takes an hour, whereas all the others and the general description state activities take 2 hours. I think that the camouflage campsite is a typo. There seems no reason it would take less time, and it would create a flow problem for the character that performed it as they'd be off step an hour with the group.
Perhaps an earlier version had the system based on one-hour increments instead of two? How would this affect the math (your statistical skills are waaay better than mine.
I've also noted that the discover and influence actions of the companion clock in at an hour each. That might be by design, but it seems like you could rocket your influence with a companion and be the best of buddies in 2-3 days.
