> It makes me wonder if any WPM threshold is enough to convince people to make the switch from Qwerty. No. You don't switch for speed. You switch for comfort and to reduce strain. The reason why the 120WPM speed is brought up at all is to (1) demonstrate that the keyboard design isn't totally bunk, and (2) that the person has spent enough time with the keyboard to get to a level of mastery with it that their opinion on the keyboard is coming from a place of knowledge.
