My personal experience is that I was getting notifications for a unread posts in a group or a friend posting a video. Stuff that should have been in the news feed, not a notification. Not interactions with my interactions, which was my expectation. In other words, false positives. At the same time, they changed it at some point so someone replying to a post or comment you've made doesn't create a notification unless you've been tagged. False negatives. No, the notifications they were sending were low quality.
