One reason some instructors rack up large dive numbers is short dive times. I took a PADI specialty that required 4 dives. I already had the intro dive. We did three 20 minute dives on one tank. We didn't get out of the water. Debriefing and rebriefing were done at the surface. When we got done the other student and the instructor had to leave. I dove solo on my second tank because neither one would stay and I didn't have anyone else to buddy up with.
