This appears to do the exact same thing as "Preferential Treatment", but the other program has a better designed, less confusing interface.

The main problem here is a confusing non-standard interface. Apparently when I check a checkbox it runs the test. These should just be changing options, not actually running the thing! In the meantime, had I not wanted to change any options, I might not have been able to find out how to actually run the test!

Still, competition is good -- keep working at it.
