The flight

What the tracklog shows, and which crossings scored.

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).14:15:00
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%
Points on offer for the day886.4 pts

1000 × 1.00 × 1.00 × 0.8864 = 886.4

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).
Your speed section time1:41:38

Timed from your 14:15:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:16:43.

Fastest time in class (among pilots who made goal)1:01:40
Time points fall off with the gap to the fastest time130.2 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.2442; × 533.2 available = 130.2 (times in hours)

Track data cleaning

347 of 8596 GPS fixes (4.0%) 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
