on Page 136 of total Warfare, the Heavy Gauss Rifle entry states that the Piloting Skill Roll modifier for weight class does not stack with itself, so shooting Two HGR while moving in a Assault Mech doesn't make it Two -2 PSRs. Does this also apply to any other rolls that may be required such as from damage. I.E. Should you shoot 2 Heavy Gauss rifles and take 20+ damage that turn, do you make Three PSRs at +0 to the Target Number, or do you make Two PSRs at +0 and one PSR at +1?
