The flight
What the tracklog shows, and which crossings scored.
Day quality — points on offer
Task validity 94.94% of a perfect day, so 949.4 of 1000 points were available.
30 pilots flew out of 30 present. Nominal launch is 96%, so launch validity is full once 29 pilots are in the air.
Measured against a 35.0 km nominal distance, a 30% nominal goal and a 5.0 km minimum distance. The field flew 26.7 km past the minimum on average, with a best of 57.7 km.
The fastest pilot took 1:11:53 against a nominal task time of 1:30:00 — 79.9% of nominal.

Track data cleaning
26 of 1126 GPS fixes (2.3%) 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
