The flight

What the tracklog shows, and which crossings scored.

How this works

Crossed the start cylinder boundary 13 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.
…and 1 more crossings
The 15:04:14 crossing is the scored start. By the 15:17:59 crossing the flight had already reached TP3 (TOWONG), 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 42.6% of a perfect day, so 426.2 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%

44 pilots flew out of 46 present. Nominal launch is 96%, so launch validity is full once 45 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.75.3%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 14.7 km past the minimum on average, with a best of 30.0 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 44 pilots flew; you flew 30.0 km, further than 28 of them. The day averaged 14.7 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.56.6%

The fastest pilot took 34:40 against a nominal task time of 1:30:00 — 38.5% of nominal.

Points on offer for the day426.2 pts

1000 × 1.00 × 0.753 × 0.566 = 426.2

Split between the components: 16 of 44 pilots made goal — a goal ratio of 0.36

distance 210 · time 216.1

The share each component takes of the day

distance 49.3% · time 50.7%

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

Full distance — one of 16 pilots in goal

How this works

Task distance30.0 km

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

Scored distance30.0 km

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

Best distance in class30.0 km
Made goal — full available distance points.210 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 30.0 km of the class best 30.0 km, worth 210 of 210.

Time points

86.9 of 216.1 pts

10th fastest of 16 through the speed section

How this works

Your speed section time59:16
Fastest time in class34:40

Set by Trent Brown — you were 24:36 behind.

Time points fall off with the gap to the fastest time86.9 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.402; × 216.1 available = 86.9 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 24:36 behind the fastest time, which cost 129.2 of the 216.1 time points on offer.

Total

297 of 426.2 pts

How this works

Distance + time + leading + arrival, minus penalties297 pts

210.0 + 86.9 ≈ 297 — the points above are shown rounded to 0.1; the total is rounded from their exact sum.
