Hmm, nah lowering that didn't seem to do much. Probably some leftover value from fallout.

Yeah, I tried it out too, not much effect. Only thing that comes to mind are some variables related to AI behavior, aggression and energy level, if I'm remembering right. On an unrelated note, there's also a "jumpingbonus" actor value, but it doesn't seem to do anything, I guess its left over from Oblivion maybe?
