HUMPHREYS COMPARES THE HARDNESS OF VARIOUS MINERALS ONLY TO SHOW THAT PRESSURE HAS LITTLE EFFECT ON DIFFUSIVITIES OF OTHER HARD MATERIALS. |
Yet he never establishes a connection between hardness and diffusivity. Why is that? Because, as has been pointed out many times, hardness does not correlaate with diffusivity. Humphreys is presenting a red herring.

The real beauty (if there is any) of the experiment is that, if (and that's a big if) it can be replicated in other studies and on other zircons, RATE may have come up with an interesting anomaly. It's far from refuting anything. "We don't know yet" is, albeit unsatisfying, is a scientific explanation that's way up on the list of explanations compared to your and Humphreys' "it's magic".
