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.
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 73.97% of a perfect day, so 739.7 of 1000 points were available.

Time points

Time points use the 5⁄6 speed-fraction exponent (the current FAI S7F, S7F §11.2).

Fastest time in class46:45
Time points fall off with the gap to the fastest time223.7 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.748; × 299.1 available = 223.7 (times in hours)

Leading points

18.2 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.18.2 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

25.1 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.25.1 pts
