I think you missed the point. It's not about which visitors get the best feature. It's about how to get people to PUSH THE BUTTON!!!!! Which is kind of the opposite of the best feature. The goal is to make people do something they don't want to do.
Figuring out best features is a completely different problem.
I didn't say it was the best for the user. Really the article misses this by comparing a new UI feature to a life-saving drug, but it doesn't matter. The point is, whatever metric you're targeting, do you use this algo or fixed group sizes?
