The difference is that this test is optional. I was just perusing the competition to see what it was all about. Who wants to spend all that time reading the instructions for a test I might not even bother to take? I clicked the link to download an input file, and then realized that doing so caused me to fail that question. Not a good experience. After encountering something else that was the slightest bit confusing, I just gave up on the whole thing.
