Monster Respawns

[Colino]

So... I've been trying to figure out forever how the respawn of monsters is determined.

In XI it was 16 minutes~? Depending on the zone you were in too.

But in XIV... I just don't even know. If you've ever tried farming an item from a monster that has only a few spawns you'll notice that it you can kill it and get a respawn 20 seconds later or not get a respawn for like 30 minutes!

Do they work like the roaming NMs work? A set spawn time of the game day that they can spawn multiple times in or something?

Does anyone have any research done on this?

I'm unsure of the details but I think it works on a population based system? Also SE has been frequently changing monster locations and spawn rates with the updates so it's kind of hard to tell.
