The flight

What the tracklog shows, and which crossings scored.

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.
Start time taken: gate 2 of 6 — the last start gate at or before the crossing. The speed-section clock runs from the gate, not from the crossing (FAI S7F §8.3.1).14:15:00

Day quality — points on offer

Task validity 95% of a perfect day, so 950 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?95%

Scored distance13.2 km

Measured along the optimized task line, up to the furthest point on course.

Best distance in class67.8 km
Linear half — half the available points scale with your share of the best distance33.9 pts

0.5 × (13.17 km ÷ 67.79 km) × 349.3 = 33.9

Difficulty half — rewards flying past stretches where many pilots landed57.4 pts

The difficulty curve is built from where the whole field landed out (FAI S7F §11.1.1).

Time points

0 pts
Time points are only awarded to pilots who reach the end of the speed section.

Leading points

0 pts
Leading 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 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.0 pts
