It was a semi circle airspace not a full circle as the scoring
software thought

I asked Petr Polách:

So why did they originally give you and 31 other pilots zeros on the first day
for going into airspace and then cut that list down to many fewer pilots? Bird
sanctuary airspace I saw.

He wrote back:

Error in software. The half sphere airspace was counted as a
circle. They solved it by manual check of all the tracklogs.
