The flight

What the tracklog shows, and which crossings scored.

Start time taken: gate 1 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).13:45:00

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%

Scored distance41.8 km

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

Best distance in class80.6 km
Linear half — half the available points scale with your share of the best distance173.3 pts

0.5 × (41.832 km ÷ 80.569 km) × 667.4 = 173.3

Difficulty half — rewards flying past stretches where many pilots landed206 pts

The difficulty curve is built from where the whole field landed out (FAI S7F §11.1.1).

Time points

0 pts
Time points are only awarded to pilots who reach the end of the speed section.

Leading points

27.5 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.27.5 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

0 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.0 pts

Track data cleaning

16 of 7951 GPS fixes (0.2%) carried an implausible altitude and were repaired before analysis — flagged by vertical-speed limits (no barometric channel to cross-check). Positions and times are never altered. How data cleaning works
