The usual ratio I've seen - at least in tailhook squadrons - is 1.5 crew-to-plane. e.g., we had four planes, 18 FOs and 12 pilots. The Bug squadrons had 12 planes and 18 pilots. And so on.
So since there's more planes than aircrew, squadrons set their own policy on how and when you get your name on a plane. We didn't get our names on a plane until we qual'ed as CAPC/CICO, pilots under the cockpit windows and FOs on the fuselage just forward of the prop-arc-warning stripe. The Corrosion divvo kept a list by seniority, so when one guy left the squadron, the next one on the list took his place.
They tried to implement that "your name on it, you do dailies" idea. Didn't really take.
