The flight

What the tracklog shows, and which crossings scored.

How this works

Crossed the start cylinder boundary 19 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.
…7 more crossings…
The 16:07:24 crossing is the scored start — the last one made, so it supersedes every earlier crossing.

Day quality — points on offer

Task validity 30.342% of a perfect day, so 303.4 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%

12 pilots flew out of 12 present. Nominal launch is 96%, so launch validity is full once 12 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.36.638%

Measured against a 20.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 3.6 km past the minimum on average, with a best of 12.2 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 12 pilots flew; you flew 10.4 km, further than 9 of them. The day averaged 3.6 km past the 5.0 km minimum, against a 20.0 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.82.817%

Nobody completed the speed section, so the spec compares distance instead: the best distance of 12.2 km against the 20.0 km nominal distance.

Points on offer for the day303.4 pts

1000 × 1.00 × 0.36638 × 0.82817 = 303.4

Nobody reached the end of the speed section, so this task offered no time or arrival points at all (FAI S7F §11).273.1 pts

Only distance and leading points could be won: 273.1 + 0 = 273.1 of the 303.4 the day was worth. The rest is not shared out to the other components — the specification leaves it unawarded.

Split between the components: 0 of 12 pilots made goal — a goal ratio of 0.00

distance 273.1 · time 0

The share each component takes of the day

distance 90.0% · time 0.0%

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

How this works

Task distance17.9 km

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

Scored distance10.4 km

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

Best distance in class12.2 km
Linear half — half the available points scale with your share of the best distance116 pts

0.5 × (10.36 km ÷ 12.2 km) × 273.1 = 116

Difficulty half — rewards flying past stretches where many pilots landed129.8 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 10.4 km of the class best 12.2 km, worth 245.8 of 273.1.

Time points

0 pts

How this works

Nobody in this class reached the end of the speed section, so the task offered no time points to anyone (FAI S7F §11). Distance and leading points were all that could be won.
