The flight

What the tracklog shows, and which crossings scored.

How this works

Crossed the start cylinder boundary 11 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 14:03:50 crossing is the scored start. By the 14:33:29 crossing the flight had already reached TP3 (THOWGL), so treating that as a re-start would mean flying the course again from there — a shorter, later run that scores less.
Start time taken: gate 1 of 5 — the last start gate at or before the crossing. The speed-section clock runs from the gate, not from the crossing (FAI S7F §9.2.4.1).14:00:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 94.94% of a perfect day, so 949.4 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%

30 pilots flew out of 30 present. Nominal launch is 96%, so launch validity is full once 29 pilots are in the air.

Distance validity — the day counts for less if the field as a whole did not get far.100%

Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 26.7 km past the minimum on average, with a best of 57.7 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 30 pilots flew; you flew 57.7 km, further than 18 of them. The day averaged 26.7 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.94.94%

The fastest pilot took 1:11:53 against a nominal task time of 1:30:00 — 79.9% of nominal.

Points on offer for the day949.4 pts

1000 × 1.00 × 1.00 × 0.9494 = 949.4

Split between the components: 12 of 30 pilots made goal — a goal ratio of 0.40

distance 446.7 · time 502.7

The share each component takes of the day

distance 47.1% · time 52.9%

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

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 57.7 km of the class best 57.7 km, worth 446.7 of 446.7.

Time points

230.3 of 502.7 pts

8th fastest of 12 through the speed section

How this works

Your speed section time1:43:22

Timed from your 14:00:00 start gate to the end of the speed section (FAI S7F §9.4) — you crossed the start at 14:03:50.

Fastest time in class1:11:53

Set by Rohan Holtkamp — you were 31:28 behind.

Time points fall off with the gap to the fastest time230.3 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.4582; × 502.7 available = 230.3 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 31:28 behind the fastest time, which cost 272.4 of the 502.7 time points on offer.
