The healing rules in the Core Rulebook seem to the the same as the ones from Dark Heresy, in that if you are Lightly Wounded, you recover 1 (or your toughness bonus for complete rest) per day, 1 (or your toughness bonus for complete rest) per week for Heavily Damaged, etc.
But this does not take into account the accelerated healing that their gene-seed bestows on them. Shouldnt they be healing at a much, much faster rate? I've seen accounts of Space Marines taking massive damage in combat, and already starting to heal on their way home.
How should this be handled?
