A/B Testing - Google Analytics Custom Variable Stats Incorrect

On http://www.recordingconnection.com , I have the A/B Theme Testing plugin configured with two themes. The plugin is correctly outputting the custom variable code in wp_footer(), and I have the Google Analytics asynchronous code in <head>.

In Google Analytics, out of 913 visits for the day, I am only showing 6 visitors with the Custom Variable set.

Is there something I could be doing wrong?
