The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 11 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 6 — 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).14:45:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 95% of a perfect day, so 950 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?100%
Time validity — was the winning time long enough relative to the nominal time?95%

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).
Your speed section time1:24:55

Timed from your 14:45:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:45:43.

Fastest time in class (among pilots who made goal)1:12:01
Time points fall off with the gap to the fastest time441.6 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.662; × 594.9 available ≈ 441.6 — the figures are shown rounded; the points come from their full precision (times in hours)
