I recently picked up a copy of Psionic Institutes; T4 isn't my usual edition, but I thought the book might be useful for other points in the timeline. I'm not sure if I missed something while reading through the book, but I didn't see any use of the generated Departmental Quality (DQ) other than needing a number greater than 0 for the department to exist. Everything in the book seems to run off the overall Quality of Institution (QI) with no reference to DQ. Did I miss something (either in this book, another book, or errata), or does DQ serve no purpose at all?
