This may be a useless post since it just reiterates, but I feel strongly that I should re-emphasize that yes, _very small tweaks_ can make the threshold 20% or 5%, so the number is essentially pulled out of a hat.

A good way to explore these problems is to perform monte carlo simulations over the set of possible parameters and then derive general behaviour from that -- looking in particular for 'catastrophic' features in the phases space. Later you can narrow your data set down based on empirically observed parameters. As an undergraduate I wrote a standard grid-based model of epidemics which does this. So it's not as though it's rocket science.
