Tasks like Precision Navigation or Navigation with Unknown Legs are based on gate scores. In the case of a 200 m gate radius (400 m wide) a pilot flying 201 m away from the central point loses all his score in the gate. Losing all the score by 1 m is always disappointing for the pilots and makes the scores rather random. To mitigate this randomness, a large amount of gates must be defined, analysed and scored.
As an alternative, a gate may lose its value gradually. For example, when gate radius is 200 m (400 m wide) the zero-value radius may be 300 m and the gate value would decrease gradually between 200 and 300 m. A pilot crossing 201 m away from the central point would score 99% of the gate value, 50% at 250 m, 1% at 299 m and zero when the distance is larger than 300m.
This is not mandatory but an option for the director. In fact, current gate scoring is only a particular case of the proposed system, in which the gate width and the zero-value width are the same.
