Sorry to disappoint. I have done a few A/B tests in my time, but that doesn't necessarily mean I have a comparable that I can share for any element which could possibly be A/B tested.

I would also caution you that, hypothetically assuming I had a comparable here, I might be a little hesitant to say "An A/B test in June 2010 of the behavior of elementary school teachers on summer holiday ready to get their Back to School Bingo started is a great way to predict the behavior of poor startup geeks contemplating a recurring billing arrangement."

The point of A/B testing isn't to anoint someone as the local genius on design and conversion optimization. The takeaway -- over and over and over again -- is that your local genius is routinely wrong about applying their old experience or intuition to new problems.

People pay me good money for advice on things like this question. I give answers, appropriately couched as "My best guess as to how this will play out". A lot of them whiff when exposed to actual customers.
