The forum stats says 199,929 total posts, though...POsts have been deleted. That stat only shows posts that still exist.
I believe the post count value is outdated in the database... that happens even in the most reliables forum systems because some specific concurrent updates happens.The forum auto recounts all statistics every week or so, just to make sure they're not off.
Legend just need maybe run "UPDATE statistics_table SET post_count = 2xx [WHERE if needed]"
This however is from the forum stats not counting posts that have been removed.
