The flight

What the tracklog shows, and which crossings scored.

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.
Start time taken: gate 2 of 3 — 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).14:00:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 100% of a perfect day, so 1000 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?100%

Distance points

667.4 pts
Scored distance80.6 km

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

Best distance in class80.6 km
Made goal — full available distance points.667.4 pts

Time points

158.5 pts
Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).
Your speed section time2:55:20

Timed from your 14:00:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:00:59.

Fastest time in class (among pilots who made goal)2:31:09
Time points fall off with the gap to the fastest time158.5 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.599; × 232.8 available ≈ 158.5 — the figures are shown rounded; the points come from their full precision (times in hours)

Leading points

50.4 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.50.4 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

17.8 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.17.8 pts
