The only way using `GetUnitMark` might cost you a mark is if the way you use it is incorrect or particularly confusing or inelegant, in which case it might cost you that style mark. I can only guess at how you intend to use it, and while I think there is a nicer alternative, I doubt you will lose a mark for doing so.
