The flight

What the tracklog shows, and which crossings scored.

How this works

Start time taken: gate 4 of 6 — 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).13:00:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 89.58% of a perfect day, so 895.8 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%

48 pilots flew out of 48 present. Nominal launch is 96%, so launch validity is full once 47 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 45.4 km past the minimum on average, with a best of 58.4 km.

How far the field got — the spread distance validity is computed from, one dot per pilot. 48 pilots flew; you flew 58.4 km, further than 13 of them. The day averaged 45.4 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.89.58%

The fastest pilot took 1:02:57 against a nominal task time of 1:30:00 — 70% of nominal.

Points on offer for the day895.8 pts

1000 × 1.00 × 1.00 × 0.8958 = 895.8

Split between the components: 35 of 48 pilots made goal — a goal ratio of 0.73

distance 330.7 · time 565.2

The share each component takes of the day

distance 36.9% · time 63.1%

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 35 pilots in goal

How this works

Task distance58.4 km

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

Scored distance58.4 km

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

Best distance in class58.4 km
Made goal — full available distance points.330.7 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 58.4 km of the class best 58.4 km, worth 330.7 of 330.7.

Time points

480.8 of 565.2 pts

5th fastest of 35 through the speed section

How this works

Your speed section time1:09:13

Timed from your 13:00:00 start gate to the end of the speed section (FAI S7F §9.4) — you crossed the start at 13:01:36.

Fastest time in class1:02:57

Set by Scott Barrett — you were 6:16 behind.

Time points fall off with the gap to the fastest time480.8 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.8508; × 565.15 available = 480.8 (times in hours)

The curve is the time-points formula — every dot is a pilot, sitting exactly on it. You were 6:16 behind the fastest time, which cost 84.4 of the 565.2 time points on offer.

Total

811.5 of 895.8 pts

How this works

Distance + time + leading + arrival, minus penalties811.5 pts

round(330.7 + 480.8, 1 dp) = 811.5
