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 3 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.

Flew 3.7 km, less than the 5.0 km minimum — scored as the minimum distance.
Scored distance5.0 km

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

Best distance in class45.6 km
Linear half — half the available points scale with your share of the best distance24.8 pts

0.5 × (5.0 km ÷ 45.6 km) × 452.1 = 24.8

Difficulty half — rewards flying past stretches where many pilots landed61.3 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
