I set up a test in Google Website Optimizer that has a 3 variations - original (A), B, and C. In order to further validate the results of the test, I added a variation C that is exactly the same as the original. And thats where the results get weird.
6 days into the test, the best performing variation is C. It outperforms the original by 18.4%! How is that possible?
Do I now discount the results of this test entirely?
