The flight

What the tracklog shows, and which crossings scored.

Crossed the start 3:12 before the first start gate opened at 13:30:00 — an early start ("jumping the gun", FAI S7F §12.2). The speed-section clock runs from the first gate.

Day quality — points on offer

Task validity 100% of a perfect day, so 1000 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%

49 pilots flew out of 49 present. Nominal launch is 96%, so launch validity is full once 48 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.100%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 32.4 km past the minimum on average, with a best of 70.1 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 49 pilots flew; you flew 7.6 km, further than 11 of them. The day averaged 32.4 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.100%

The fastest pilot took 1:56:14 against a nominal task time of 1:30:00 — the task took as long as it was meant to, so no time devaluation applies.

Distance points

125 of 534 pts

38th furthest of 49

How this works

Task distance70.1 km

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

Scored distance7.6 km

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

Best distance in class70.1 km

Linear half — half the available points scale with your share of the best distance29.1 pts

0.5 × (7.64 km ÷ 70.08 km) × 534 = 29.1

Difficulty half — rewards flying past stretches where many pilots landed95.8 pts

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

The curve is the distance-points formula, half of it built from where the field landed out (FAI S7F §11.1.1) — 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 7.6 km of the class best 70.1 km, worth 125 of 534.

Time points

0 of 326.2 pts

How this works

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

Leading points

0 of 81.6 pts

37th best of 46 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 longer6.811

Best in class 1.936.

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; × 81.6 available = 0

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

The curve is the leading-points formula — every dot is a pilot, sitting exactly on it. Your coefficient of 6.811 against the class best of 1.936 puts you at 0 of 81.6.

Arrival points

0 of 58.3 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

15 pilots reached the end of the speed section on this task; the points scale with where in that group you crossed it (FAI S7F §11.4).

Penalty

-96.2 pts

Jump the gun (FAI S7F §12.2): started 3:12 before the first start gate. The complete flight is scored, with 1 penalty point per 2 seconds early; the total never drops below the minimum-distance score.−96.2 pts

192.3 s early ÷ 2 s per point = 96.2 points

Total

104.2 of 1000 pts

How this works

Distance + time + leading + arrival, minus penalties104.2 pts

125.0 + 0.0 − 96.2 jump-the-gun would come to 28.8, but the jump-the-gun penalty never drops a pilot below the minimum-distance score (FAI S7F §12.2) — so the total is 104.2.

Spread across distance-points, time-points, arrival-points, leading-points and penalties — distance-points the largest, at 409.

Start cylinder (SSS): The circle around the start turnpoint. The race clock begins when you cross it in the required direction, or at the start gate you took.
Speed section: The timed part of the task: from the start to the end of the speed section. Time points are earned here, and only here.
End of speed section (ESS): Where the clock stops — usually a cylinder shortly before goal, so pilots are not racing all the way to the ground.
Optimized task line: The shortest legal way around the turnpoints, clipping each cylinder rather than flying to its centre. Every distance on this page is measured along it.
Made good: How far along that line you got — not how far you flew. Wandering off course adds kilometres to your track but none to your distance made good.
Minimum distance: A floor: a pilot who flies less than this is scored as if they flew it, so a short flight is never worth less than nothing.
Nominal distance / time / goal / launch: What the organiser expected of a good day — a typical task length, duration, share of pilots in goal, and share of pilots launching. They are the yardsticks the day is measured against, not targets anyone must hit.
Validity: How much of a full 1000-point day this task was worth. A day where few launched, nobody got far, or the winner was round very quickly counts for less in the overall standings.
Goal ratio: The share of flying pilots who made goal. It decides how the day's points are split between distance and the other components.
Leading coefficient: A measure of how much of the race you spent out in front, as an area under your distance-over-time curve. Lower is better; the absolute number means nothing on its own, only the comparison does.
Distance difficulty: Hang gliding only: half the distance points are weighted by where the field landed out, so getting past a stretch that stopped many pilots is worth more than easy kilometres.
Jump the gun: Starting before the first start gate opened. Paraglider pilots are scored only to the start cylinder; hang glider pilots take a penalty that grows with how early they were.
