i think that is covered by defineing the percentages you want. this is all just off the top of my head. it's the way i implemented things in my map generator, and they both do similar things and seem to work in roughly the same fashion.

so don't take my word for it, it's just an educated guess. you might try 5 or so runs with the default values and then do another batch with the ruggedness significantly higher to see what kind of effect it has.
