User blog comment:Lepton Adapter/Meta: What a growth rate is/@comment-33713741-20181127215753/@comment-30754445-20181128012147

You don't really need to "know the hierarchy up and down" to get the general gist of a growth-rate statement that uses the FGH. You just need to memorize the order of the rounder ordinals (like the fact that "gamma-0" comes after "epsilon-0") and that's much easier than it seems at first glance.

If even this seems like a too daunting task, you can use my Psi Levels scale, which basically converts ordinals to ordinary numbers (while preserving their order). Whenever someone mentions an ordinal, just look it up on this table. Do that a few dozen times, and before you know it you won't even need the table anymore.

BTW I have an offline friend who is very casually interested in googology. When discussing the topic with him, I find myself constantly refering to my Psi Levels whenever I'm refering to an ordinal. It helps him not to get completely lost in the vast world of large numbers and ordinals. In the last week alone, I must have used "Level 150" to refer to the BHO over half a dozen times.
