The flight

What the tracklog shows, and which crossings scored.

Start time taken: gate 3 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).14:30:00

Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 88.25% of a perfect day, so 882.5 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?88.25%

Scored distance52.0 km

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

Best distance in class52.0 km

Time points

253.1 pts

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

Your speed section time1:14:37

Timed from your 14:30:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:31:43.

Fastest time in class1:01:10

Time points fall off with the gap to the fastest time253.1 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.7147; × 354.1 available = 253.1 (times in hours)

Leading points

48 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.48 pts

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

Arrival points

17.7 pts

Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.17.7 pts
