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.
Start time taken: gate 4 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).15:00:00
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 time1:51:22

Timed from your 15:00:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 15:11:22.

Fastest time in class (among pilots who made goal)1:07:56
Time points fall off with the gap to the fastest time61.9 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.2267; × 273 available = 61.9 (times in hours)
