  • Find (determine, (This is BIG issue)) what the true centerline(s) are.This can be affected by hasty or uneven trimming @ tips or other extremities.Just because you make a line that is equidistant of your measurements does not mean That is true center.All you have is a 'geographic center' (I just invented that 8-) ) eg: You measure the H-stab,divide by two and calculate 'center'.Or do you?
