Many, many post no or a few posts, and a few post many posts

According to my counter machine I have posted 5077 posts, but according to my section “user’s posts” I have posted 5081 posts. So the counter machine has not always done its job perfectly. If it had done its job perfectly, it would have shown me the number “5081”. In reality I have posted even more than 5081 posts, but those more posts have been deleted accidently by a moderator.
