The flight
What the tracklog shows, and which crossings scored.
Crossed the start cylinder boundary 5 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%
