What Calyspo model are you referring to? The earliest used a diaphragm first stage, and the later versions were a balanced piston design. That said, a slow creep of 5psi, which then remains stable wouldn't bother me. Some modern regs even specify that a small amount of creep is permissible.

Glad to help. I have a Calypso VI that I originally purchased around 1978. It is rebuilt, and I still make dives with it each year.
