This task tracks the second AC of T172291: Launch page previews A/B test on enwiki and dewiki.
- Verify the bucketing method: Around 50% of sessions sending Popups events should have popupEnabled = 1.
- (modified from earlier condition - bucketing is by session, not by pageview)
- Done in T175377#3605918
- We verify that the sampling rates on enwiki and dewiki are correctly enforced per @Pcoombe's question:
We're seeing some odd results here, although I don't think it's related to the eventlogging issues you mention. Quick question: can you confirm what percentage of people should be seeing hovercards? And does that match what you're seeing in your logging?
