Quiz Summary coming 'soon'. Until then:
Following are the results I obtained from running my test script against
everyone's submissions. (I had to fix minor bugs in a few to make them
work.) After that is the (updated) test script.
The script runs a full day of time against the class, advancing the time
uniformly by different numbers of seconds.
For each result, the first line reports whether the class was generally
fast or slow. (The maximum possible variation is 50% fast or slow.)
The second line is the result of recording, each time the fuzzy time
changed, how many minutes ahead or behind the actual time the change
occurred. Ideally, you should see the same percentages spread along the
whole range.
I didn't test Louis Scoras' submission, because it took a (good, but)
different track for displaying the time, so I knew it wouldn't pass any
of my tests.
