Regeneration Question

[RedDragon]

Hey all,
Let's say I want to make a character that heals much faster than a normal person, but only when receiving medical care and with bedrest. This would create somebody who is just as vulnerable in combat as anyone else, but can get back on the field much more quickly, and potentially survive injuries that would kill most. How would I stat this? I'm thinking Regeneration with Accessibility, but I'm not sure what value it should have. On a related note, how do Very Rapid Healing and Regeneration interact? Do you pay the 10-pt difference between Rapid Healing and Very Rapid Healing, or does Regeneration make that redundant?
