How often are open site explorer reports updated?

[seagreen]

I collect the information contained in open site explorer reports and csv backlinks audits on the 15th of every month.  I noticed that the numbers are unchanged from 9/15-10/15.  How often are the reports typically updated?

"Our goal is to update the data at least every 4 weeks."

There's an update due on the 18th, also worth following SEOMoz on Twitter/Facebook as they tend to post an update once Linkscape has been updated.
