Actually, it does, because of the investment required to produce a brood,
which is related to brood size and investment per egg, not on survivorship.
What I think you meant to say was that an appropriate level of
survivorship to the next generation for a given reproductive output can be
achieved either by producing fewer young with higher survivorship chances,
more young with lower chances or something in between - these strategies
are presumably selectively equivalent and will be appropriate depending on
the nature of the beast we are talking about.
