Hi, question about adding an additional variant to a current live experiment. We have an experiment with 100% users targeting, with 3 variants. We need to add variant 4. What would be the best practice to do it? To modify a current experiment or to add another experiment rule with all 4 variants (and I guess reducing the coverage of Rule 1 from 100%).

Hi Veronika 👋 The recommended practice here is to create a new experiment with the new variant. Adding a new variant to an experiment already in progress can lead to compromised result data.
