What about a lord with no knights, or a lord with 5 knights? If this score is made to mean anything, and the scale is exponential, it'll just incite the realm to micro-manage knights to dump as many of them in as few regions as possible. On the other hand, if it's not exponential, then it'd be nothing more than a noble count meter.
Certainly nothing can be as micro-managerial as having the devs corral all the characters on one side of the continent. On the other hand, this promotes increased density in a way that is player-driven and is analogous to RL. A lord with 5 knights is inherently more powerful than a lord with none. The current landscape does nothing to incentivize lords to attract knights to their region, which is why most regions have none. So we can leave it to the devs to come up with what I respectfully consider misguided projects to increase density artificially, like the glacier experiment, or we can make it so that having knights is something lords actually want. I don't see that leading to micro-management because it would be the lords who have the most to gain.
