Table size differences - anything look unusual?

So I thought I was having a database crisis, long story short it doesn't appear I am. I compared table sizes for my current installation and a two week old backup. A few tables seemed to drop in size which caught my eye and I'm not sure if I should be concerned or not.

Left columns contain data on the changed tables, right columns on the current database.

Do any of the size decreases look unusual or alarming?

In particular - xf_conversation_message, xf_liked_content, xf_post, xf_thread, xf_thread_user_post, xf_thread_watch, xfa_blog_comment and others have decreased (with some change in rows).

Can anyone comment on this?

For example, does the change in values for xf_post indicate a significant loss of actual forum posts? In this case we're talking about 50,000 rows and 170MB.

Thanks guys.
