The sharpness of the gravity gradient is reliant on the difference between the mass being simulated and the actual mass. The smaller it is, the less the maximum gradient can be. All else being equal, a cubic metre of iron can be propelled faster than a cubic metre of copper.
Umm, am I misreading this or shouldn't that be 'The smaller it is, the more the maximum gradient can be'?
