We have a Segment - Amplitude events pipeline.
Recently I found that the unique number of page views in Segment differs from Amplitude.
I take all page views and GROUP BY COALESCE(UserId, AnonymousId)
Simply a segmentation by `Views` (Page event) + Unique users.
The difference is about 20%, so I’m trying to figure out which value is correct, or how is the unique number is calculated?
