Except that the potato paradox doesn’t apply here. What the business cares about is total signups and revenue, not the variation in rate of signups. The potato paradox only applies if you’re talking about the rate of misses, which, while interesting, is secondary or tertiary in importance. An 80% decrease in missed signups only causes about a ~5% increase in revenue. That’s an important point if the team that produced that 5% revenue increase costs a large amount of money to run. At close to a million a year for the team, that’s only going to be worth it for some. And that was the whole point of the article: this optimization usually isn’t worth the cost.
