Enter the email address you signed up with and well email you a reset link. After the initial statistics, the same stats are reported but for a result where a specific item is dropped. However, you can run it on single factor just to get the omega total statistic, but any less than three factors will produce a warning and some metrics will either be unavailable or not make much sense.
