Under your Experiment "Timing" tab, you select "Target Audience" to be 25%, 50%, 75%. This will start the A/B split setup:
- You will be prompted for your "Success Metric"
- You will be prompted to join an existing split of create a new split.
- The other part of a new split will be a "Control" (a 'do nothing') - this is your App's normal behaviour as a champion.
- This "control" is automatically created
- You can see the performance chart to compare the Experiment vs the "Control" under your chosen "Success Metric" in the dashboard.
