East coast, most midwest count all points. West coast hunters usually count one side then the other.
Old school hunters do not count the browtines or eye guards. Those are the old boys I love to listen to as they will say I shot a 6X6 (really an 8X8) or 7X7 (9X9). The pictures are a freak of nature... They never have any interest in getting the racks scored.
My 2 cents.
