The only posts that don't count toward a person's total post count are those in Daily Chatter and you aren't a member there so unless the post was removed, all posts should count. When I get a chance I'll check to make sure our post count settings haven't been changed by recent updates - don't think so but I'll check. If it has, I'll update the settings and get the system to "recount" everyone's posts.
Thanks for asking about this Moka ...
