The bad part about the timing is once you kill a boss you basically "own it". The respawn times are not fixed but are predictable .... once you've killed it, there's a small number of windows during which it will pop again.
And, yes, once you know where it pops and the windows when it will pop, it makes it very, very hard for new players to discover the same information.
