The flight

What the tracklog shows, and which crossings scored.

How this works

Start time taken: gate 1 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).12:15:00

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 15.5 km, further than 4 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.

Task distance58.4 km

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

Scored distance15.5 km

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

Linear half — half the available points scale with your share of the best distance44 pts

0.5 × (15.533 km ÷ 58.435 km) × 330.7 = 44

Difficulty half — rewards flying past stretches where many pilots landed44.5 pts

The difficulty curve is built from where the whole field landed out (FAI S7F §12.1.1).

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 15.5 km of the class best 58.4 km, worth 88.4 of 330.7.

Time points

0 of 565.2 pts

How this works

Time points are only awarded to pilots who reach the end of the speed section.
