The flight

What the tracklog shows, and which crossings scored.

How this works

Crossed the start cylinder boundary 3 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 15:02:28 crossing is the scored start. By the 16:53:24 crossing the flight had already reached TP5 (PINEMT), 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 4 of 4 — 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).15:00:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 100% of a perfect day, so 1000 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%

34 pilots flew out of 34 present. Nominal launch is 96%, so launch validity is full once 33 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 45.7 km past the minimum on average, with a best of 73.5 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 34 pilots flew; you flew 73.5 km, further than 16 of them. The day averaged 45.7 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.100%

The fastest pilot took 1:56:35 against a nominal task time of 1:30:00 — the task took as long as it was meant to, so no time devaluation applies.

Points on offer for the day1000 pts

1000 × 1.00 × 1.00 × 1.00 = 1000

Split between the components: 18 of 34 pilots made goal — a goal ratio of 0.53

distance 411.5 · time 588.5

The share each component takes of the day

distance 41.2% · time 58.8%

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

Scored distance73.5 km

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

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 73.5 km of the class best 73.5 km, worth 411.5 of 411.5.

Time points

537.1 of 588.5 pts

4th fastest of 18 through the speed section

How this works

Your speed section time2:01:04

Timed from your 15:00:00 start gate to the end of the speed section (FAI S7F §9.4) — you crossed the start at 15:02:28.

Fastest time in class1:56:35

Set by Scott Barrett — you were 4:29 behind.

Time points fall off with the gap to the fastest time537.1 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.9127; × 588.5 available = 537.1 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 4:29 behind the fastest time, which cost 51.4 of the 588.5 time points on offer.

Total

How this works

Distance + time + leading + arrival, minus penalties948.6 pts

round(411.5 + 537.1, 1 dp) = 948.6
