The change to an affliction's Healing Rate from one Course Test, by normalized success level: CF −2, MF −1, MS +1, CS +2.
A failure (below MARGINAL_SUCCESS) worsens the rate by one more than its level's distance from marginal, and a success improves it by its level.
The normalized success level (−1 CF … 2 CS).
The signed change to apply to the Healing Rate.
