When I go directly to a user's profile and see all their posts, sometimes one of their posts isn't in my timeline where it should be. I follow less than 100 users on Bluesky, but I guess this explains why I occasionally don't see a user's post in my timeline.
Lossy indeed.
If another user you follow reposted or replied to a post, it can affect its order in your following feed. You shouldn't be seeing any loss as described in the article from following only 100 users.
