At first I was going to leave the highlighted part alone, but the more I assessed Chaos' answer, the more I began to figure that leaving it that vague would probably leave more questions than answers (this isn't Chaos' fault, of course, because he only knows what he knows).

In regards to the highlighted part only:

How do we measure this? What level of wounds/injuries would constitute an average healer tapping out due to Focus depletion? What level of wounds/injuries would constitute a group of average healers tapping out due to Focus depletion? How can we reasonably measure what 'get some work done' means?

I know it's asking for specifics, but his answer may leave too much up to interpretation, and may cause some... Chaos (heh).
