Shortest landing should have full power on with wheels at ground + 2ft, about 20 ft before end of runway/paddock. Dependig on power available and wing loading/design, airspeed can be stall - 10kts at that point. Closing the throttle/s wil result in an immediate and "firm" touchdown. Try a fully loaded (maybe a bit more than fully) Aztec into 1600 ft of strip with 15 kts of tailwind and a vertical rockface for the over-run. No possible go-round, great incentive to stop short.
