5 VU or less is the range on a Hit-and-Run attempt.<br/><br/>Active Auguries would have been necessary to determine he was straining his engines. But please don't blame me for the fact that a 12 speed ship going 13/turn would shed 1 Speed by burning retros, and a 2 speed ship going 99/turn (theoretically) would shed 97 speed with the exact same maneuver (and neither of them would need to roll for it).
