I hope we have a much cleared statement of the numbers for qualification. Things like "top 25%" leave a lot to the imagination.
Sure, the top 25% of 100 is 25. But with the very small number of CL scale entries the rounding-off factor is huge.
If you build a plane and travel to a contest you have no control of the number of entries.
What is an "entry"? Paying the entry fee? Static judging? Attempting flight? Getting a score?
Last year Brodak only reported those who got scores, which was less than half of the actual entries.
I would suggest a "top 3" minimum with additional qualifiers for larger contests.
The 2016 NASA Classic was a great contest. But we don't need rules that make it even smaller. We only used two and a half of three available days.
