Yes, the devs can. But they don't care, because they're trying to replicate the classic implementation, which had variance. They're actually more likely to make it worse than remove it, as there's a bug report here asking for 14 hour variance:

You can address this with a player agreement, but trying to convince the devs to do this to stop wasting people's time is not a very likely direction for actually accomplishing something.
