Hi Luis,

I think the problem is that "startup time" is not necessarily well defined,
so I think that is why the current behavior is what it is. I agree though
that it is quite confusing and should be documented, or I think even
improved because it now prevents quickly joining replacement nodes if the
number of them does not hit the required limit.

I created a ticket: https://github.com/akka/akka/issues/15411
