If "gaming" the system means less recidivism, that sounds good to me.

Prison ships to Australia were originally paid per passenger that boarded in Britain. The death rates were horrible, in the double-digit percentages. When the transport ships were instead paid per passenger that _arrived_ the death rates went down phenomenally.

And someone like you might say: "omg these prison ships gamed the system by saving lives!!!" Yes, that's what we want to happen.
