Fair enough, but IMO if they are holding themselves to that narrow and frankly completely useless condition then 90% of the episode was wasted effort talking to people about things that, by the definition of their own condition were completely unrelated.
I wouldn't consider 46 degrees to be a predominantly vertical trajectory, but its closer to being that than it is horizontal. I'd bet money that people have been injured by bullets between 46 and 70 degree angles at least. I wouldn't rule out higher angles than that either.
It could end up having less energy sooner than I imagine, but I would have to see it simulated far more convincingly than they did on the show.
