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 55.81% of a perfect day, so 558.1 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%

47 pilots flew out of 47 present. Nominal launch is 96%, so launch validity is full once 46 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.55.81%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 13.6 km past the minimum on average, with a best of 67.6 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 47 pilots flew; you flew 5.0 km, further than 0 of them. The day averaged 13.6 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.100%

The fastest pilot took 2:20:43 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

66.7 pts

How this works

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

Task distance67.6 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 class67.6 km

Linear half — half the available points scale with your share of the best distance17.2 pts

0.5 × (5.0 km ÷ 67.6 km) × 464.5 = 17.2

Difficulty half — rewards flying past stretches where many pilots landed49.5 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.

Leading points

0 pts

How this works

Leading points reward flying out front during the speed section. A manual flight has no tracklog to measure leading from, so it earns none.0 pts

Arrival points

0 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

2 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).

Behind Stuart Cathcart−491.4 pts

Most of the gap — 397.8 of 491.4 points — is distance.

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.
