Use monthly-plan renewals to set a warning threshold for yearly-plan test winners

Sara Grana… like an immediate effect that you can see. And then always after some months, recheck the cohort. What has happened with these people? Sometimes it's a bit frustrating because you have the majority of users buying a 12-month subscription, so you won't see it until later on. But maybe there's something that you can do if you see that the one month behaving in a particular way, maybe you can assume that the same would happen for the 12 months.

If the one month was to renew at this 10% less or 5% more, whatever you want based on the result of your test, what would happen. And then you can know once you have some really easy way to check in a way, in a sense. You keep an eye, okay, if this goes below 10, then I know we are in trouble. I know that probably the winner is actually the loser.
