I’m trying to calculate the average number of times a specific event (let’s call it Event A) occurs per post for each user in Amplitude. Each occurrence of Event A has an associated article_id property that identifies the post.

When I use Event Segmentation and group by article_id for Event A, I can see the average number of Event A per post, but not the average across all posts for each user. Any detailed steps or guidance on how to achieve this would be greatly appreciated!
