The behavior of the leaderboard benchmarks has me puzzled.  Can anyone help me understand the following?

\n

Benchmark #2 (the best on the leaderboard) is described as:

\n

2- all flights fly at 17,500 ft at 500 mph to destination

\n

The next best benchmark is #3, which is described as:

\n

3- all flights fly at 17,500 ft at 1000 mph to destination

\n

Benchmark #2 and #3 get exactly the same score, even though the second plane is flying 1000 mph. How is that possible?  (I could understand it being more or even less, but why exactly equal?)

\n

Next, the 1000 mph velocity in benchmark #3 is supersonic, and I don't think most commercial airliners are designed for that.  Nevertheless, is that a valid speed for a submission? 

\n

In addition, there are some benchmarks (e.g. #5) where the flight's velocity is 0 mph:

\n

5- all flights fly at 17,500 ft at 0 mph to destination

\n

Is a 0 mph velocity permitted? (and what does that really mean?)  I'm also puzzled why a 0 mph plane scores better than benchmark #8, where the plane is moving 500 mph:

\n

8- all flights fly at 31,000 ft at 500 mph to destination

\n

Any comments, anyone?  

\n

PS I wasn't in Flight-Quest #1, so perhaps I'm missing something fundamental...

Those were the results of very old tests that shouldn't have been showing up - don't draw any meaning from them. They have been removed now, apologies for the confusion.
