The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 9 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.
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 44.71% of a perfect day, so 447.1 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?60.45%
Time validity — was the winning time long enough relative to the nominal time?73.97%

Time points fall off with the gap to the fastest time150.8 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.6865; × 219.6 available = 150.8 (times in hours)

Arrival points

7.1 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.7.1 pts

Track data cleaning

2 of 2543 GPS fixes (<0.1%) 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
