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 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).15:15:00
Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 88.64% of a perfect day, so 886.4 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?88.64%

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).
Your speed section time1:14:15

Timed from your 15:15:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 15:15:53.

Fastest time in class (among pilots who made goal)1:01:40
Time points fall off with the gap to the fastest time346.8 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.6503; × 533.24 available = 346.8 (times in hours)

Track data cleaning

22 of 7897 GPS fixes (0.3%) 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
