I had a “leveling” system for computable large numbers as well! But mine is more spread out: ε0 is level 12, Γ0 is level 18, BHO is level 23, Buchholz ordinal is level 25, ψ(ψΙ(0)) is level 28, Small Rathjen ordinal is level 32, Mahlo Cardinal OCFs are levels ~39 to ~49, Stage Cardinal diagonalizers in OCFs are level ~55, and the limit of DAN is level 72 (subject to change).

My T array function reaches level 24 in my system, and 13 in yours.
