Excerpt from the original CRV Manual Paul H. Smith:

The mechanism developed to allow the system to be put on “hold,” providing the opportunity to flush out AOLs, deal with temporary inclemencies, or make system adjustments, allowing a fresh start with new momentum. There are seven types of breaks: analytic overlay (AOL), aesthetic impact (AI), AOL-Drive (AOLD), personal inclemency (PI), bilocation (Bilo), confusion (Conf), and too much (TM).
