Mr. Page makes a lot of hypotheses, as well. He confirmed as much when he appeared before the committee on February 17. So you were citing his hypothesis.
Furthermore, it is somewhat unfortunate that your research did not take into account practices in other countries. I would have really liked to know whether this measure is in place anywhere else. And if so, I would want to know if those countries got rid of the measure because it did lead to higher prisons costs and ultimately served no purpose except to turn people into criminals. There is absolutely no information on that, and I find it unfortunate.
