UNIT Z

(an arrangement of the Academy) your Z is doing the kingpin or the top activity that is done in the Academy, which is in this particular case, as we are dealing with HCA/HPA, a Problems Intensive, and when they can do a Problems Intensive from one end to the other of course that's your Class 2a auditor, but they're auditing in Unit ZA and ZB.
