The flight

What the tracklog shows, and which crossings scored.

Start time taken: gate 1 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).12:15:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 89.58% of a perfect day, so 895.8 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?89.58%

Scored distance58.4 km

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

Best distance in class58.4 km

Time points

20.3 pts
Time points use the 5⁄6 speed-fraction exponent (the current FAI S7F, S7F §11.2).
Your speed section time2:00:39

Timed from your 12:15:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 12:15:54.

Fastest time in class1:02:57
Time points fall off with the gap to the fastest time20.3 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.05135; × 394.6 available = 20.3 (times in hours)

Leading points

71.6 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.71.6 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

28.6 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.28.6 pts

Total

452.6 pts
Distance + time + leading + arrival, minus penalties452.6 pts

332.2 + 20.3 + 71.6 + 28.6 ≈ 452.6 — the points above are shown rounded to 0.1; the total is rounded from their exact sum.
