The flight

What the tracklog shows, and which crossings scored.

No valid start — the track never crossed the start cylinder in the required direction, so only pre-start progress can score.

Day quality — points on offer

Task validity 29.36% of a perfect day, so 293.6 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%

3 pilots flew out of 3 present. Nominal launch is 96%, so launch validity is full once 3 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.38.79%

Measured against a 25.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 5.0 km past the minimum on average, with a best of 20.1 km.

Time validity — the day counts for less if the fastest pilot got round much quicker than the task was meant to take.75.69%

The fastest pilot took 48:11 against a nominal task time of 1:30:00 — 53.6% of nominal.

Distance points

94.1 pts

How this works

Flew 0.0 km, less than the 5.0 km minimum — scored as the minimum distance.

Task distance20.1 km

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

Scored distance5.0 km

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

Best distance in class20.1 km

Linear half — half the available points scale with your share of the best distance18.7 pts

0.5 × (5.0 km ÷ 20.13 km) × 150.8 = 18.7

Difficulty half — rewards flying past stretches where many pilots landed75.4 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 5.0 km of the class best 20.1 km, worth 94.1 of 150.8.

Time points

0 pts

How this works

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

Spread across 2 components.

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.
