The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 3 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 1 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).12:15:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 89.58% of a perfect day, so 895.8 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?100%
Time validity — was the winning time long enough relative to the nominal time?89.58%

Time points use the 5⁄6 speed-fraction exponent (the current FAI S7F, S7F §11.2).
Your speed section time1:46:02

Timed from your 12:15:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 12:15:15.

Fastest time in class (among pilots who made goal)1:02:57
Time points fall off with the gap to the fastest time144.5 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^5⁄6) = 0.2564; × 563.7 available = 144.5 (times in hours)

Track data cleaning

18 of 9527 GPS fixes (0.2%) carried an implausible altitude and were repaired before analysis — flagged by vertical-speed limits (no barometric channel to cross-check). Positions and times are never altered. How data cleaning works
