Spot landing (timed) scoring

*2.C2 SPOT LANDING - TIMED*

The score will be the value of the strip in which both main wheels touch down (PS) plus the distance between the finish of the deck and the closest wheel, scored 1 point per whole metre (PD). Touching down on a dividing line scores the higher of the two strips. If the aircraft touches down on a full minute, the time being taken from the official clock, ±5 seconds a further 100 points is scored (PT). This score will be reduced by 5 points for every second outside ±5 seconds from a full minute.

\[...\]

Thus the score calculation will be (PS+PD+PT) x 250/450 with a maximum score of 250

The score will be the value of the strip in which both main wheels touch down with the ground (PS) plus the distance between the finish of the deck and the closest wheel, scored 1 point per whole metre (PD). Touching down on a dividing line scores the higher of the two strips. If the aircraft touches down on a full minute, the time being taken from the official clock, ±5 seconds a further 100 points is scored (PT).

The score will be the value of the strip in which both main wheels touch down (PS) plus the distance between the

finish of the deck and the closest wheel, scored 1 point per whole metre (PD). Touching down on a dividing line

scores the higher of the two strips. If the aircraft touches down on a full minute, the time being taken from the

official clock, ±5 seconds a further 100 points is scored (PT). This score will be reduced by 5 points for every

second outside ±5 seconds from a full minute.

h3. Reason

The wording for the scoring formula is misleading. Some believe it has to be normalised and others don't. That is probably the reason why the scores in some championships are further normalised to give 250 points to the best pilot, and the fraction 250/450 simply doesn't appear in the formula.

So there are two problems:

* If the scores +are not+ normalised to 250, then no pilot would ever get 250 points as long as nobody will ever land in less than 1 m

* If the scores +are+ normalised to 250, then some pilot would get 250 points, even in a case where all pilots are very bad and the best one lands on the 100 pt strip, way off the round minute and barely manages to stop in the deck.

This proposal has three effects:

* To simplify and clarify the scoring system

* To make the scoring always absolute, an individual value independent from what other pilots achieve, as it happens when neither stopping distance nor time is measured.

* To increase the task value to 450, accounting for the fact that a short stop at at the right time is inherently more difficult than simply stopping in the deck at any moment.
