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 99.3% of a perfect day, so 993 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?99.3%

Time points

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

Fastest time in class1:25:04
Time points fall off with the gap to the fastest time213.2 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.525; × 406 available = 213.2 (times in hours)

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

34.1 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.34.1 pts
