The difference in frame physical properties and energy transmission is definitely measurable, just as aero, weight and any other physical attribute is. The data is with Scott's engineers, and whoever endeavors to conduct a comprehensive analysis and comparison. Whether or not I find data remains to be seen. Whether the differences are significant or negligible remains to be seen as well.
I'm not speculating, I'm searching for information.
