Does Hard Target stack with the Run modifier?

By killridemedly, in Dark Heresy Rules Questions

Meaning, if a character had the Talent 'Hard Target', would the modifier for Hard Target (-20 to BS Tests when using Run or Charge) stack with the normal modifier for Run (-20 to BS Tests) thus making any running character with Hard Target at a -40 BS to hit? Or does Hard Target only extend the Run modifier over to Charge?

By RAW it's unclear, but I'd have to say yes. If they meant the running modifier to not be affected, they wouldn't even have mentioned it in "Hard Target."
