The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 3 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 3.33% of a perfect day, so 33.3 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?30.88%
Time validity — was the winning time long enough relative to the nominal time?10.79%

Time points fall off with the gap to the fastest time2.6 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.170; × 15.4 available = 2.6 (times in hours)

Track data cleaning

7 of 3099 GPS fixes (0.2%) 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

  • 15:06:07 · 1 fix · up to 121 m off
  • 15:06:57–15:06:59 · 3 fixes · up to 709 m off
  • 15:07:13–15:07:15 · 3 fixes · up to 180 m off
