Example: Opportunist: [...] If you succeed by 3 or more, return Opportunist to your hand after this test instead of discarding it.
When does it count as succeeding by 3? Do I succeed by 1 if I match the difficulty of the skill, or would that be considered succeeding by 0? Other way around: If the difficulty is 2, would I need 4 or 5 to succeed by 3?
We understand it the way that you need at least 5 to return the card...
