I remember him campaigning for this for a long time, presenting evidence and meeting consistent criticism and resistance from one opinionated trainer who was wrong, was shown to be wrong, and who I have observed to be wrong since at least one third of the time. Still, that combination of arrogance and ignorance is a doozy.
