That's making a few assumptions there. The user would have to do 
that every single time to ensure they don't miss posts, or assume 
that the server always returns the last N posts and thus 
carefully count the number of new posts that arrive in one batch.

I would imagine the answer to be one of:

- implementing RFC 5005 (on both sides)

- the user is not fulfilling their side of the assumptions which 
the feed "protocol" is based upon, and therefore cannot expect to 
observe an uninterrupted feed

- the user is putting too much faith on a vanishing standard 
which was never designed to work in a pub/sub fashion, as it does 
not have the necessary "all entries since <timestamp>" (or 
similar) operation as part of the protocol.
