The flight

A manual flight report — no tracklog.

Manual flight — recorded by an official for a pilot with no tracklog (FAI S7F §8.4). The distance is computed from the last turnpoint reached and the landing point, exactly as a real track at the same place would score.

Last turnpoint reached: Takeoff — ELLIOT

Day quality — points on offer

Task validity 63.98% of a perfect day, so 639.8 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%

27 pilots flew out of 27 present. Nominal launch is 96%, so launch validity is full once 26 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.68.92%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 14.6 km past the minimum on average, with a best of 46.0 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 27 pilots flew; you flew 5.0 km, further than 0 of them. The day averaged 14.6 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.92.83%

The fastest pilot took 1:07:56 against a nominal task time of 1:30:00 — 75.5% of nominal.

Distance points

142.4 pts

How this works

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

Task distance46.0 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 class46.0 km

Linear half — half the available points scale with your share of the best distance20 pts

0.5 × (5.0 km ÷ 45.956 km) × 366.74 = 20

Difficulty half — rewards flying past stretches where many pilots landed122.4 pts

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

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.
