Scores computed

No valid start — 133.8 points

The flight

What the tracklog shows, and which crossings scored.

No valid start — the track never crossed the start cylinder in the required direction, so only pre-start progress can score.

Day quality — points on offer

Task validity 78.365% of a perfect day, so 783.7 of 1000 points were available.

Launch validity — did enough registered pilots launch?100%
Distance validity — did the field fly far enough relative to the nominal distance?78.44%
Time validity — was the winning time long enough relative to the nominal time?99.904%
Points on offer for the day783.7 pts

1000 × 1.00 × 0.7844 × 0.99904 ≈ 783.7 — the validity factors are shown rounded to 5 decimal places; the points on offer come from their full precision.

Best distance in class50.1 km
Linear half — half the available points scale with your share of the best distance22.4 pts

0.5 × (5.0 km ÷ 50.1 km) × 449.2 = 22.4

Difficulty half — rewards flying past stretches where many pilots landed111.4 pts

The difficulty curve is built from where the whole field landed out (FAI S7F §11.1.1).

Time points

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

Track data cleaning

38 of 1695 GPS fixes (2.2%) carried an implausible altitude and were repaired before analysis — flagged by vertical-speed limits (no barometric channel to cross-check). Positions and times are never altered. How data cleaning works
