I am unclear how to apply the following sentence from the Treat Wounds skill action:
If you succeed at your check, you can continue treating the target to grant additional healing. If you treat them for a total of 1 hour, double the Hit Points they regain from Treat Wounds.
Does this mean after 6 successful Treat Wounds checks (10 minutes each = 1 total hour of treatment), additional Treat Wounds checks are twice as effective at restoring HP?
For some reason, this sentence isn't clear to me. Thanks to anyone who can help clarify the intent of this rule.
