The flight

What the tracklog shows, and which crossings scored.

This task has no start (SSS) turnpoint — the first turnpoint is treated as the start.
Crossed the start cylinder boundary 29 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.

Time points

90.5 pts
Time points use the 5⁄6 speed-fraction exponent (the current FAI S7F, S7F §11.2).
Your speed section time2:06:44
Fastest time in class1:18:05
Time points fall off with the gap to the fastest time90.5 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.2475; × 365.8 available = 90.5 (times in hours)

Leading points

0 pts
Leading points reward flying out front during the speed section — the pilot with the best leading coefficient takes all available leading points, others fall off with the gap.0 pts
Measured with the classic squared-distance leading coefficient (S7F §11.3.1, the hang-gliding / GAP2016–2018 variant).

Arrival points

18.9 pts
Arrival points reward crossing the end of the speed section early relative to the other pilots who reached it.18.9 pts

Total

Distance + time + leading + arrival, minus penalties561.6 pts

452.1 + 90.5 + 18.9 ≈ 561.6 — the points above are shown rounded to 0.1; the total is rounded from their exact sum.
