Are the Vials always going to be off? I have always used two vials, but when I first started I tested the results by reversing their roles and it was the same. My thoughts were that if it was slightly of, it would be a repeatable difference so if it was off .005 due to glass variation, it would always be off 005.
Am I missing something?
