@pratik That will vary based on what's going on in your M.b timeline. Basically Lillihub get's what you see in the main web app from the API. A mix of posts and mentions.
Lillihub asks the API for a list of 60 items and then takes that list and separates it. if you are looking at the timeline page it discards all the mentions. If you are looking at the conversations page it gets rid of the posts. Also, the conversation page only shows a conversation once. So if the people you follow are all commenting on the same conversation you'll see even less.
That's also the reason when you move page to page on Conversations you might see the same one pop up again, that conversation was referred to in an earlier set of items.
Hopefully that makes sense 😄
