I seem to recall back when Bridget was running it and then Eric, that they asked you to dive at least once every 12 months, if not they might ask you to monitor the class (no cost).
I remember that policy and it was scrapped a couple years ago. My old manual set the requirement at 4 hours a year. The major concern was that you wouldn't be able to pass the buoyancy dive after a long break. Another reason was to get more volunteer dives out of people who took the class.
