I don't know how they came up with a negative number here, but they found a way.

I feel like they're a little incentivized to scapegoat the rock for more of the falling recruitment than is really true. Because he can be replaced and they can just go "whoopsie, let me try that again!", whilst the alternative is admitting the army's own behavior has tarnished it's reputation so badly that nothing they can do will salvage the generational bad blood they have created.
