What the tracklog shows, and which crossings scored.

How this works

Day quality — points on offer

Task validity 1.176% of a perfect day, so 11.8 of 1000 points were available.

How this works

Launch validity — the day counts for less if much of the field never got into the air.77.514%

4 pilots flew out of 6 present. Nominal launch is 96%, so launch validity is full once 6 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.4.635%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 0.9 km past the minimum on average, with a best of 6.7 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 4 pilots flew; you flew 6.0 km, further than 1 of them. The day averaged 0.9 km past the 5.0 km minimum, against a 35.0 km nominal distance.
Time validity — the day counts for less if the fastest pilot got round much quicker than the task was meant to take.32.732%

The fastest pilot took 14:49 against a nominal task time of 1:00:00 — 24.7% of nominal.

Points on offer for the day11.8 pts

1000 × 0.77514 × 0.04635 × 0.32732 = 11.8

Split between the components: 1 of 4 pilots made goal — a goal ratio of 0.25

distance 6.8 · time 3.4 · leading 0.9 · arrival 0.6

The share each component takes of the day

distance 58.2% · time 29.3% · leading 7.3% · arrival 5.2%

Leading weight follows the FAI S7F 2026 §11 formula: 18% of the non-distance weight (the task's Leading Time Ratio) goes to leading.

Distance points

6.5 of 6.8 pts

3rd furthest of 4

How this works

Task distance6.7 km

The optimized task line — the shortest legal way round the turnpoints.

Scored distance6.0 km

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

Best distance in class6.7 km
Linear half — half the available points scale with your share of the best distance3.1 pts

0.5 × (6.0 km ÷ 6.7 km) × 6.84 = 3.1

Difficulty half — rewards flying past stretches where many pilots landed3.4 pts

The difficulty curve is built from where the whole field landed out (FAI S7F §12.1.1).

The curve is the distance-points formula, half of it built from where the field landed out (FAI S7F §12.1.1) — every dot is a pilot, sitting exactly on it. Its steepest stretches are the ones fewest pilots got past, so flying through one is worth more than the same distance somewhere easy. You flew 6.0 km of the class best 6.7 km, worth 6.5 of 6.8.

Time points

0 of 3.4 pts

How this works

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

Leading points

0 of 0.9 pts

3rd best of 4 measured leading coefficients

How this works

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.0 pts
Your leading coefficient — the area under your distance-over-time curve, so lower means further ahead for longer0.905

Best in class 0.139.

Leading points fall off with the gap to the best coefficient0 pts

leading factor = max(0, 1 − ((LC − LCbest)² ÷ LCbest)^1⁄3) = 0.000; × 0.9 available = 0

Your flight ended before the end of the speed section, so the graph carries on at your best distance until maxTime15:05:17

maxTime is when the last pilot landed out. That was after the last pilot reached the end of the speed section, so the clock kept running.

Measured with the squared-distance leading coefficient (S7F §12.3.1, the hang-gliding variant).
The curve is the leading-points formula — every dot is a pilot, sitting exactly on it. Your coefficient of 0.905 against the class best of 0.139 puts you at 0 of 0.9.

Arrival points

0 of 0.6 pts

How this works

Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.0 pts
1 pilot reached the end of the speed section on this task; the points scale with where in that group you crossed it (FAI S7F §13.5).
