The flight

What the tracklog shows, and which crossings scored.

How this works

Crossed the start cylinder boundary 5 times. The scored start is the latest crossing from which the flight still makes its best run along the course — re-starting supersedes an earlier start, while simply flying back through the cylinder later in the task changes nothing.
The 14:00:52 crossing is the scored start. By the 14:25:33 crossing the flight had already reached TP2 (KANGCK), so treating that as a re-start would mean flying the course again from there — a shorter, later run that scores less.
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 53.22% of a perfect day, so 532.2 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%

26 pilots flew out of 26 present. Nominal launch is 96%, so launch validity is full once 25 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.71.95%

Measured against a 50.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 21.0 km past the minimum on average, with a best of 33.1 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 26 pilots flew; you flew 33.1 km, further than 14 of them. The day averaged 21.0 km past the 5.0 km minimum, against a 50.0 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.73.97%

The fastest pilot took 46:45 against a nominal task time of 1:30:00 — 52% of nominal.

Points on offer for the day532.2 pts

1000 × 1.00 × 0.7195 × 0.7397 = 532.2

Split between the components: 12 of 26 pilots made goal — a goal ratio of 0.46

distance 233.5 · time 261.4 · arrival 37.3

The share each component takes of the day

distance 43.9% · time 49.1% · arrival 7.0%

Leading weight follows the FAI S7F 2026 §11 formula: 18% of the non-distance weight (the task's Leading Time Ratio) goes to leading.

Distance points

233.5 of 233.5 pts

Full distance — one of 12 pilots in goal

How this works

Task distance33.1 km

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

Scored distance33.1 km

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

Best distance in class33.1 km
Made goal — full available distance points.233.5 pts
The curve is the distance-points formula, half of it built from where the field landed out (FAI S7F §12.1.1) — 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 33.1 km of the class best 33.1 km, worth 233.5 of 233.5.

Time points

182.2 of 261.4 pts

8th fastest of 12 through the speed section

How this works

Your speed section time59:23
Fastest time in class46:45

Set by Hughbert Alexander — you were 12:38 behind.

Time points fall off with the gap to the fastest time182.2 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.697; × 261.4 available = 182.2 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 12:38 behind the fastest time, which cost 79.2 of the 261.4 time points on offer.

Arrival points

12.3 of 37.3 pts

7th of 12 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.12.3 pts
Reached the end of the speed section 7th of 1215:00:16

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 rank12.3 pts

arrival ratio = 1 − (7 − 1) ÷ 12 = 0.50; arrival factor = 0.2 + 0.037·r + 0.13·r² + 0.633·r³ = 0.330; × 37.3 available = 12.3

One place earlier would have been worth 2.3 more points

The curve is front-loaded: first place takes all 37.3 available, and everyone else who reaches the end of the speed section keeps at least 7.6 of them.

The curve is the arrival-points formula — every dot is a pilot, sitting exactly on it. You arrived 7 of 12, worth 12.3 of 37.3 — one place earlier would have been 2.3 more. The order is by the clock at the end of the speed section, not by speed.
