I've been monitoring a number of spawn points and they're very precise, repeating the pattern each hour.
Do you mean that the same pokemon are spawning within an hour window, say, 2 pidgey, a weedle, and an oddish at 15 minute intervals, or that the timing is precise but random pokemon spawn?
I would agree that it's precise, but occasionally the game throws a rare pokemon in when I'd expect something more common; time of day seems to be an obvious factor in types of pokemon appearing, too, but I'm not sure if that's coincidental or not.
