Delayed threads (and disabled posts) counts in BoardListPage statistics

Delayed threads not count in forum's statistics but yes count in general statistics (BoardListPage statistics). Works as designed? I think a thread not posted (delayed) should not count.

Edit: The same applies to the disabled posts.

Quote from Alexander Ebert

Considering the thread/post state appear to make sense at a first glance, but this rises a few downsides:

• Despite we have separate database columns to track disabled/deleted with an index, it slows down the queries required to retrieve the data
• Disabling/Deleting a thread/post require the cache to be discarded and rebuild every time
• In a small forum (lets say a few thousand posts) this can make a difference, but in the average forum and above the numbers won't really change

Especially the second item in the list is a good reason to ignore the thread/post state and considering the almost inexistent impact on the actual outcome we have ultimately decided against.

I like to read a good explanation. Thanks.
