The flight
What the tracklog shows, and which crossings scored.
This task has no start (SSS) turnpoint — the first turnpoint is treated as the start.
Crossed the start cylinder boundary 5 times. The scored start is the latest crossing from which the flight still makes its best run along the course — re-starting supersedes an earlier start, while simply flying back through the cylinder later in the task changes nothing.

Task validity 73.97% of a perfect day, so 739.7 of 1000 points were available.
Launch validity — did enough registered pilots launch?100%
Distance validity — did the field fly far enough relative to the nominal distance?100%
Time validity — was the winning time long enough relative to the nominal time?73.97%

Measured along the optimized task line, up to the furthest point on course.
Best distance in class33.1 km
Linear half — half the available points scale with your share of the best distance112.2 pts
0.5 × (23.79 km ÷ 33.11 km) × 312.4 = 112.2
Difficulty half — rewards flying past stretches where many pilots landed118.5 pts
The difficulty curve is built from where the whole field landed out (FAI S7F §11.1.1).
Time points
0 ptsTime points are only awarded to pilots who reach the end of the speed section.
Leading points
0 ptsLeading points reward flying out front during the speed section — the pilot with the best leading coefficient takes all available leading points, others fall off with the gap.0 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).
Arrival points
0 ptsArrival points reward crossing the end of the speed section early relative to the other pilots who reached it.0 pts
