The maximum is set to 32 50 (in one batch/a day?).

Earlier the site got an update that lets you add a Profile Tab on Facebook and gives you a short URL for your Docs folder. 
ProfileTab ShortURL
For the short URL, Docs uses your FB vanity URL. If you don’t have one, Docs uses your FB user ID.

Ready to invite your friends to Docs (and/or Add a Profile Tab on Facebook)? You will find quick access to both features at the bottom right of the home page.
