The flight

What the tracklog shows, and which crossings scored.

Start time taken: gate 2 of 5 — 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 88.25% of a perfect day, so 882.5 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?88.25%

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).
Your speed section time1:18:38

Timed from your 14:15:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:17:10.

Fastest time in class (among pilots who made goal)1:01:10
Time points fall off with the gap to the fastest time321.3 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.564; × 498 available ≈ 321.3 — the figures are shown rounded; the points come from their full precision (times in hours)
