And just to wrap up my story line:

Got an unrestricted 1st Class at the 27 month mark. The extra 3 months over the standard 24 month wait were due to the red tape, waiting times, etc related to waiting on OKC.

Working with the Doc in Tulsa helped, but in the end we only got the requirement for 2 EEGs removed (just had to do 1), as well as the need for Full Core Battery testing (submitted a very, very strong Cog Screen).
