Suppose the event stream for a single user is:
- Monday: ImpressionEvent #1 topic=(none)
- Tuesday: ImpressionEvent #2 topic=dogs
- Wednesday: ImpressionEvent #3 topic=cats
If I group-by ‘topic’ for the last 7 days, which value is used for the grouping? What about filter?
What I’m seeing is that the earliest value of `topic` is used in the group-by → but that has the consequence that some users with topic=(none) in the segmentation chart, actually have topic=cats when you inspect the user profile page.
Is this the expected behavior of am I doing this wrong?
