I updated the calculation I'd ran for you a while back to include the average depth of continental crust, rather than the minimum, as that seems to have been the values used for measurements regarding the parameters for those brackets in the Tiering System. Of most note for you, this makes the low-end of the feat about baseline 6-A rather than High 6-B+. That's all.
