The flight

What the tracklog shows, and which crossings scored.

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).14:45:00

Completed the task — full task distance is credited.

Day quality — points on offer

Task validity 95% of a perfect day, so 950 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?95%

Points on offer for the day950 pts

1000 × 1.00 × 1.00 × 0.95 = 950

Time points use the 2⁄3 speed-fraction exponent (the older GAP2016/2018 curve, S7F §11.2).

Your speed section time1:48:44

Timed from your 14:45:00 start gate to the end of the speed section (FAI S7F §8.7) — you crossed the start at 14:55:13.

Fastest time in class (among pilots who made goal)1:12:01

Time points fall off with the gap to the fastest time228.6 pts

speed fraction = max(0, 1 − ((T − Tbest) ÷ √Tbest)^2⁄3) = 0.322; × 594.9 available ≈ 228.6 — the figures are shown rounded; the points come from their full precision (times in hours)

Total

583.7 pts

Distance + time + leading + arrival, minus penalties583.7 pts

round(355.1 + 228.6, 1 dp) = 583.7

Track data cleaning

1 of 2912 GPS fixes (<0.1%) 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
