The passive skill for the Kumano class says +100% crew heal but it is not programmed correctly. +100% should mean I heal at double rate but instead it means I heal back to full no matter how badly my crew is hurt. In a recent fight, Genari focused marines on me and had my crew down to roughly 60/215. I was back to 215/215 the next round. I have no pertinent medical skills modifying the situation.
