Overland/Public Dungeon Boss loot cooldown

Is how often can I loot a boss really established? I've read numerous threads and opinions on the internet about this but there isn't a general consensus. Some say you have to wait 2 min from your last boss loot to loot any boss again, which I found is certainly not the case. What I've found to be the most propable is that you need to wait some time for each boss. For example if you run Crows Wood and go fight as fast as you can undisturbed all the bosses, you will gain drops from every single one of them regardless of waiting time. But if you e.g. kill Buron, go kill Shriek and then go back to Buron you most propably won't get loot unless you wait some time.
