In this regard, fleet size means nothing. The size of the fleet is in no way equal to the number of people who actually contribute. Case in point? The Fed fleet over which I am an Admiral; we have 70 members, but only myself and 2 others ever contribute much of anything. The rest of our members are essentially dead weight that either never log in, or never contribute of they do log in.
That's an internal problem.
