Land on the bloody threshold and if the PAPI is anything but 4 reds in a light aircraft you should be shot down
Any consideration for aerodrome design classification in your theory there? If you land on the threshold that means you will be roughly 50' at 300m from the end of the runway. That could become problematic if you start undershooting or get wind shear/down draughts. At least if you land further in from the runway end you have a small amount of buffer up your sleeve.
