The flight

What the tracklog shows, and which crossings scored.

How this works

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.
The 13:38:36 crossing is the scored start — the last one made, so it supersedes every earlier crossing.

Day quality — points on offer

Task validity 25.44% of a perfect day, so 254.4 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.100%

7 pilots flew out of 7 present. Nominal launch is 96%, so launch validity is full once 7 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.28.89%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 5.6 km past the minimum on average, with a best of 18.7 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 7 pilots flew; you flew 16.5 km, further than 5 of them. The day averaged 5.6 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.88.05%

The fastest pilot took 40:36 against a nominal task time of 1:00:00 — 67.7% of nominal.

Points on offer for the day254.4 pts

1000 × 1.00 × 0.2889 × 0.8805 = 254.4

Split between the components: 1 of 7 pilots made goal — a goal ratio of 0.14

distance 176.9 · time 54.2 · leading 13.6 · arrival 9.7

The share each component takes of the day

distance 69.5% · time 21.3% · leading 5.3% · arrival 3.8%

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

2nd furthest of 7

How this works

Task distance18.7 km

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

Scored distance16.5 km

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

Best distance in class18.7 km
Linear half — half the available points scale with your share of the best distance78.1 pts

0.5 × (16.547 km ÷ 18.73 km) × 176.9 = 78.1

Difficulty half — rewards flying past stretches where many pilots landed88.4 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 16.5 km of the class best 18.7 km, worth 166.6 of 176.9.

Time points

0 of 54.2 pts

How this works

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

Leading points

13.6 of 13.6 pts

Best of 6 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.13.6 pts
Your leading coefficient — the area under your distance-over-time curve, so lower means further ahead for longer0.392

The best in the class — no one spent more of the race out front, so this takes the full available leading points.

Your flight ended before the end of the speed section, so the graph carries on at your best distance until maxTime14:58:17

maxTime is when the last pilot reached the end of the speed section — later than the last land-out, so it sets the clock for everyone still flying.

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. You hold the best coefficient in the class, so you take all 13.6 leading points.

Arrival points

0 of 9.7 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).

Total

180.1 of 254.4 pts

How this works

Distance + time + leading + arrival, minus penalties180.1 pts

166.6 + 0.0 + 13.6 ≈ 180.1 — the points above are shown rounded to 0.1; the total is rounded from their exact sum.
