Here if you can hang a ring off it it counts as a point. I don't necessarily agree with that logic but thems the rules.
Same rules here, technically. However, a nice 6x6 bull with a teensy little tit on one side isn't usually going to be referred to as a 6x7 in most conversations. That is until it comes time to BS in the man cave, then it might come up; "notice he's actually a 6x7, got that little tit off the sword tine there."
