I still believe having an aged account helps (and at least it isn't going to hurt). But I will also admit all points come from bank currencies that are in my name, I only book for myself and less often three relatives that share my last name and are almost always flying on the same itinerary as me, etc. So I probably attract less attention in general than some others.
