The flight

What the tracklog shows, and which crossings scored.

How this works

Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 30.7% of a perfect day, so 307 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%

15 pilots flew out of 15 present. Nominal launch is 96%, so launch validity is full once 15 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.56.34%

Measured against a 20.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 5.5 km past the minimum on average, with a best of 16.3 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 15 pilots flew; you flew 16.3 km, further than 12 of them. The day averaged 5.5 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.54.49%

The fastest pilot took 33:26 against a nominal task time of 1:30:00 — 37.2% of nominal.

Distance points

193.7 of 193.7 pts

Full distance — one of 3 pilots in goal

How this works

Task distance16.3 km

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

Scored distance16.3 km

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

Best distance in class16.3 km

Made goal — full available distance points.193.7 pts

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 16.3 km of the class best 16.3 km, worth 193.7 of 193.7.

Time points

72.2 of 79.3 pts

3rd fastest of 3 through the speed section

How this works

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

Your speed section time35:55

Fastest time in class33:26

Set by Andy Schmidt — you were 2:28 behind.

Time points fall off with the gap to the fastest time72.2 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.910; × 79.3 available = 72.2 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 2:28 behind the fastest time, which cost 7.1 of the 79.3 time points on offer.

Leading points

0 of 19.8 pts

8th best of 10 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 longer4.155

Best in class 1.702.

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; × 19.8 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 4.155 against the class best of 1.702 puts you at 0 of 19.8.

Arrival points

6.7 of 14.2 pts

2nd of 3 to the end of the speed section

How this works

Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.6.7 pts

Reached the end of the speed section 2nd of 315:24:08

The arrival order is by the clock at the end of the speed section, not by speed — an earlier start gate can put a slower pilot ahead of a faster one here.

Arrival points fall off steeply with each place6.7 pts

arrival ratio = 1 − (2 − 1) ÷ 3 = 0.667; arrival factor = 0.2 + 0.037·r + 0.13·r² + 0.633·r³ = 0.470; × 14.2 available = 6.7

One place earlier would have been worth 7.5 more points

The curve is front-loaded: first place takes all 14.2 available, and everyone else who reaches the end of the speed section keeps at least 3.5 of them.

The curve is the arrival-points formula — every dot is a pilot, sitting exactly on it. You arrived 2 of 3, worth 6.7 of 14.2 — one place earlier would have been 7.5 more. The order is by the clock at the end of the speed section, not by speed.

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.
