Hmm, I was trying to go through your A/B options but it didn't seem to register any click. So I started clicking repeatedly. Then, it processed those clicks on the first 7 items, giving you bad data. FYI.
This just hit the frontpage so the server might be a bit overloaded, I'm sorry. Trying to resize resources right now. Thanks for the heads up, in the long term (ideally) noise shouldn't be a huge problem in a sufficiently large dataset (or at least I'm already expecting some noise haha)
