Not sure what you are trying to do. Maybe I don't understand the question.
After the barrel is checked for run out it is set up true to the bore on both ends and all work is done off this center line including the crown. There should be no difference in the vertical plane based on the orientation of the barrel/flutes if the barrel has little or no run out. I like to single point all crowns so they are true to the bore.
If the crown is not square with the bore it should be re cut.
On a fluted barrel it really doesn't matter what the orientation is for accuracy, it is just a matter of looks. If it is not timed one way or the other it really looks like poor workmanship.
