The flight

What the tracklog shows, and which crossings scored.

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.
Start time taken: gate 4 of 5 — 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).14:45:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 99.57% of a perfect day, so 995.7 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?99.57%

Time points

310.8 pts
Time points use the 5⁄6 speed-fraction exponent (the current FAI S7F, S7F §11.2).
Your speed section time1:40:56

Timed from your 14:45:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:46:19.

Fastest time in class1:26:36
Time points fall off with the gap to the fastest time310.8 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.7398; × 420.1 available = 310.8 (times in hours)

Leading points

22.1 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.22.1 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

29.1 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.29.1 pts
