It's not quite that simple though because you are comparing two different types of materials. {which is not directly mentioned} You have to take into account the material's modulus of rigidity. The Aussie bar is high density chrome moly and the "~22.4mm statement" was only back calculated from the first calculation to be used as a comparative tool.
