Good stuff Pete thanks, and thanks for your work. I haven't played SH3 for quite a while now, but as dumb as the escorts are and as overly affective as the silent running is, I also just many times let the game run and went to do other things while escaping an attack, etc.
I wouldn't mess with the passive settings unless you want to drive yourself crazy; dog chasing it's tail scenario that ends up being a waste of time.
