Scores computed

No valid start — 113.4 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 94.94% of a perfect day, so 949.4 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?100%
Time validity — was the winning time long enough relative to the nominal time?94.94%
Points on offer for the day949.4 pts

1000 × 1.00 × 1.00 × 0.9494 = 949.4

Track data cleaning

26 of 1126 GPS fixes (2.3%) 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
