The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 7 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.

Start time taken: gate 3 of 4 — the last start gate at or before the crossing. The speed-section clock runs from the gate, not from the crossing (FAI S7F §8.3.1).14:30:00

Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 63.98% of a perfect day, so 639.8 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?68.92%

Time validity — was the winning time long enough relative to the nominal time?92.83%

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).

Your speed section time1:33:46

Timed from your 14:30:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:31:01.

Fastest time in class (among pilots who made goal)1:07:56

Time points fall off with the gap to the fastest time123.7 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.453; × 273 available = 123.7 (times in hours)
